Simplified arguments to :py:func:`modularAnalysis.inputMdst` and :py:func:`modularAnalysis.inputMdstList`.
The arguments of :py:func:`modularAnalysis.inputMdst` and :py:func:`modularAnalysis.inputMdstList` have been changed a little. You no longer need to specify "default", it's done automatically.
The following code lines need to be changed from:
# old
import modularAnalysis as ma
ma.inputMdst("default", "/path/to/your/file.root", path=mypath)
# or
ma.inputMdst("Belle", "/path/to/your/file.root", path=mypath)To:
# new
import modularAnalysis as ma
ma.inputMdst("/path/to/your/file.root", path=mypath)
# or
ma.inputMdst("/path/to/your/file.root", path=mypath, environmentType="Belle")And similarly for :py:func:`modularAnalysis.inputMdstList`.
Warning
We no longer support MC5-10 files.
Breaking of backward compatibility for kinematic variables
The floating-point members of the Particle class (invariant mass, momentum and position components) are now stored as doubles and no longer as floats. Previously, in some edge cases like for ISR photons, in particular the energy calculation could suffer from a cancellation of significant digits. This change might slightly modify the values of (derived) kinematic variables, however it should be below most analysts sensitivity.
Track time
When reconstructing data with release-07 the new variable trackTime becomes
available, which is computed by the TrackTimeEstimatorModule. This track
time is the average time of the SVD clusters attached to the track minus the
SVDEventT0.

.. only:: not light .. rubric:: ``HepMCInput``, ``HepevtInput`` and ``LHEInput`` modules do not anymore boost the ``MCParticles`` The modules ``HepMCInput``, ``HepevtInput`` and ``LHEInput`` do not anymore boost the ``MCParticles``, and the parameter ``boost2Lab`` is now removed from the modules. These modules can not read the ``BeamParameters`` payloads from the conditions database, so having the particles boosted correctly and in a reproducible way was non-trivial. A new module, ``BoostMCParticles``, is added for boosting into the laboratory frame the ``MCParticles`` using the information stored in the conditions database. The module must be appended to the steering path just after the ``HepMCInput``, ``HepevtInput`` or ``LHEInput`` module and before running the detector simulation.
.. only:: not light .. rubric:: The jitter of the L1 trigger is included in the standard simulation The L1 trigger jitter is randomly extracted from a double gaussian whose parameters have been tuned with 2020 data. The machine filling pattern is taken into account in the simulation of the jitter.
.. only:: not light .. rubric:: The L1 trigger simulation is included in :py:func:`simulation.add_simulation` The L1 trigger simulation (``tsim``) is now executed in the standard simulation: before SVD and PXD simulation but after the simulation of the rest of the subdetectors. For this reason, the python function ``add_tsim()`` is deprecated. If you already have a ``add_simulation`` in your path, you already get L1 trigger simulation. If you do not have ``add_simulation``, and you need the L1 trigger simulation, please use :py:func:`L1trigger.add_trigger_simulation`.
.. only:: not light .. rubric:: Discontinue the support of the old "fullFormat" for cDSTs and extend the "rawFormat" cDSTs to MC The support of the ``fullFormat`` cDSTs is discontinued. :py:func:`reconstruction.add_cdst_output` does not store anymore additional branches when the option ``rawFormat=False`` is selected, being simply an alias of :py:func:`mdst.add_mdst_output`. The users have to explicitly define the additional branches they want to store using the ``additionalBranches`` parameter. The only supported format is the ``rawFormat``, that is now extended to MC. If ``rawFormat=True`` and ``mc=False`` are selected, the rawdata + tracking data objects are stored, while with ``rawFormat=True`` and ``mc=True`` the digits + tracking data objects, including the ``MCParticles`` and the relations between them and the digits, are stored.
Removal of old and deprecated database functions
Some functions used in the past to handle the conditions database (like basf2.use_local_database or basf2.reset_database) are removed, and any script using them does not work anymore.
This removal does not imply any functionality loss, since the users can use the basf2.conditions object to properly configure the conditions database in their steering files (see also :ref:`configuring_cdb`).
Photons generated by PHOTOS in continuum events
Fixed the issue where PHOTOS photons were not correctly flagged in continuum events, e.g., charm decays (:issue:`5828`).
This was present in release-05-00-01 and earlier, including MC13 files.
Unification of B2BII settings
A single switch between Belle and Belle II settings has been implemented, which is automatically set when reading in a Belle type mdst. No individual options have to be set in modular analysis functions.
Neutral hadrons from ECLClusters get momentum from the cluster energy
Since release-04 it has been possible to load ECLClusters under the neutral hadron hypothesis.
Previously we assumed a mass when calculating the particle momentum, however this leads to problems when, for example, a K_L^0 deposits less than its mass energy in the ECL. This happens about 50% of the time.
The momentum of neutral hadrons from the ECL is now set to the :b2:var:`clusterE`.
Bremsstrahlung correction
The BremsFinder module has been developed to find relations between tracks
and photons that are likely to have been emitted by these tracks via
Bremsstrahlung. The matching quality figure of merit is based on the angular
distance between the photon ECL cluster and the extrapolated hit position of
the track at the ECL. The function correctBrems performs the actual
correction. There is also a reimplementation of Belle's Bremsstrahlung
correction approach of looking for photons in a cone around tracks
(correctBremsBelle), which is recommended for b2bii analyses.
Warning
While it is technically possible to perform a TreeFit after applying Bremsstrahlung correction, the fit performance is unfortunately quite bad. However, there is already an improvement in the pipeline that should fix this issue. It will probably be available in one of the next light releases.
MC reconstruction and MC matching
The :b2:mod:`ParticleCombinerFromMC` module and its corresponding wrapper function reconstructMCDecay should be used instead of findMCDecay to reconstruct decay modes based on MC information.
The DecayStringGrammar has been extended with new exception markers for Bremsstrahlung, decay in flight, and misidentification.
Exceptions for the MC matching of daughter particles with the DecayStringGrammar are propagated to the mother particle.
Redefinition of angle variables
The kinematic variables :b2:var:`decayAngle`, :b2:var:`daughterAngle` and :b2:var:`pointingAngle` now return the angle instead of its cosine.
Protection of ParticleLists and particle combinations
It is no longer allowed to use the label "all" for a particle list if a
cut is applied. Reconstructed decays need to preserve electric charge.
However, this can be deactivated if you know what you are doing, e.g. in
searches for New Physics.
Removal of default analysis path and NtupleTools
Warning
The default path ("analysis_main") and the NtupleTools are now removed.
This is a major backward-compatibility breaking change. Please update your user scripts to create your own path (basf2.create_path) and to use the variable manager tools <variablemanageroutput> (such as VariablesToNtuple <v2nt>).
If your previously working example script from release-03 looked something like this:
from basf2 import *
from stdCharged import stdPi
from modularAnalysis import *
stdPi("good")
ntupleFile("myFile.root") # <-- now removed
ntupleTree("pi+:good", ['pi+', 'Momentum']) # <-- now removed
process(analysis_main)
print(statistics)You should update it to this:
import basf2 # better not to import all
from stdCharged import stdPi
from modularAnalysis import variablesToNtuple
mypath = basf2.Path() # create your own path (call it what you like)
stdPi("good", path=mypath)
variablesToNtuple("pi+:good", ['px', 'py', 'pz', 'E'], path=mypath)
basf2.process(mypath)
print(basf2.statistics).. seealso::
The example scripts available here:
.. code-block:: text
$BELLE2_RELEASE_DIR/analysis/examples/VariableManager
Switch of beam spot information from nominal to measured values.
The interaction point position and its uncertainties are now taken from the database with values provided by the tracking group. All beam kinematics information is also moved to the database, which will eventually be measured on data. For now they are the values provided by the accelerator.
Warning
The previous definition of the boost included a small rotation to align it with the HER. This is no longer possible with the new structure. The definition of CMS is therefore slightly changed. The impact should be at the percent level.
If you have a physics analysis sensitive to this change: please discuss with the software / performance groups and add a comment to :issue:`4294`.
.. seealso:: The beam information can be accessed with :b2:var:`Ecms`, :b2:var:`beamPx`, :b2:var:`beamPy`, :b2:var:`beamPz`, and :b2:var:`beamE`.
Note
As a consequence of this, there is now a difference between the variables ( :b2:var:`dx`, :b2:var:`dy`, :b2:var:`dz` ) compared to ( :b2:var:`x`, :b2:var:`y`, :b2:var:`z` ); and similarly for variables ( :b2:var:`mcDecayVertexX`, :b2:var:`mcDecayVertexY`, :b2:var:`mcDecayVertexZ` ) compared to ( :b2:var:`mcDecayVertexFromIPX`, :b2:var:`mcDecayVertexFromIPY` and :b2:var:`mcDecayVertexFromIPZ` ).
Redesign of the Conditions Database Interface
The configuration and handling of the connection to the conditions database has been completely rewritten in a more coherent and modular way. We now have a new and consistent configuration interface, global tag replay and advanced checks: If users specify a global tag to be used which is either marked as invalid in the database or which cannot be found in the database the processing is now aborted. See :ref:`conditionsdb_overview` for details.
Restrict usage of useDB=False for Geometry creation
Creating the geometry from XML files instead of the configuration in the
Database may lead to wrong results. So while the option useDB=False is
still necessary to debug changes to the geometry definitions it is now
restricted to only be used for exp, run = 0, 0 to protect users from
mistakes.
This also changes the behavior of add_simulation() <simulation.add_simulation> and add_reconstruction() <reconstruction.add_reconstruction>: If a list of components is provided this will now only change the digitization or reconstruction setup but will always use the full geometry from the database.
Loading ECLClusters under multiple hypotheses
It is now possible to load K_L^0 particles from clusters in the ECL. This has several important consequences for the creation of particles and using combinations containing K_L^0 s or other neutral hadrons in the analysis package. This is handled correctly by the ParticleLoader and ParticleCombiner (the corresponding convenience functions are modularAnalysis.fillParticleList and modularAnalysis.reconstructDecay). Essentially: it is forbidden from now onwards for any other analysis modules to create particles.
Deprecated RAVE for analysis use
The (external) RAVE vertex fitter is not maintained. Its use in analysis is therefore deprecated. We do not expect to remove it, but do not recommend its use for any real physics analyses other than benchmarking or legacy studies.
Instead we recommend you use either KFit (vertex.kFit) for fast/simple fits, or TreeFit (vertex.treeFit) for more complex fits and fitting the full decay chain. Please check the :ref:`TreeFitter` pages for details about the constraints available. If you are unable to use TreeFitter because of missing functionality, please submit a feature request!
Warning
The default fitter for vertex.fitVertex has been changed to KFit.
Tidy up and rename of Helicity variables.
Renamed helicity variables in the VariableManager following consistent logic. We added the new variable :b2:var:`cosAcoplanarityAngle`.
Warning
cosHelicityAngle is now :b2:var:`cosHelicityAngleMomentum`, and :b2:var:`cosHelicityAngle` has a new definition (as in the PDG 2018, p. 722).
| Old name | New name |
|---|---|
cosHelicityAngle |
:b2:var:`cosHelicityAngleMomentum` |
cosHelicityAnglePi0Dalitz |
:b2:var:`cosHelicityAngleMomentumPi0Dalitz` |
cosHelicityAngleIfCMSIsTheMother |
:b2:var:`cosHelicityAngleBeamMomentum` |
New DecayStringGrammar for custom MCMatching
Users can use new DecayStringGrammar to set properties of the MCMatching. Then isSignal, mcErrors and other MCTruthVariables behave according to the property.
Once DecayStringGrammar is used with reconstructDecay, users can use isSignal instead of several specific variables such as isSignalAcceptMissingNeutrino. If one doesn't use any new DecayStringGrammar, all MCTruthVariables work same as before.
The grammar is useful to analyze inclusive processes with both fully-inclusive-method and sum-of-exclusive-method. There are also new helper functions genNMissingDaughter and genNStepsToDaughter to obtain the detailed MC information.
You can find examples of usage in :ref:`Marker_of_unspecified_particle`, :ref:`Grammar_for_custom_MCMatching`.
Moved to C++17
The whole software including the ROOT in the externals is now compiled using the C++17 standard. This should not affect many users but there are a few rare cases where this might lead to compilation problems of analysis code as some deprecated features have been removed. The most notable are
throw(TypeName)exception specifiers, just remove them.std::auto_ptrwhich should be replaced bystd::unique_ptr- some older parts of the
<functional>header.
In particular if you compile a standalone program that links against the ROOT
in the Belle2 externals this now also needs to be compiled in C++17 mode. You
can do this by adding -std=c++17 to the compiler arguments.
Note
It's best to directly pass the output of root-config --cflags to
the compiler. That way you always pass the correct flags needed for the
particular ROOT version setup.
Build system moved to Python3
This is a major update of SCons but most users should not notice any difference except for two instances:
If you update an existing working directory from an older release you might run into an error
scons: *** [...] TypeError : intern() argument 1 must be string, not unicode scons: building terminated because of errors. TypeError: intern() argument 1 must be string, not unicode: [...]
In this case please remove all
.scon*files in the top level of your software directory and rerunsconsIn the unlikely case that you have custom
SConscriptfiles which are not Python 3 compatible you will have to :ref:`update them <python:pyporting-howto>`.
