  • L1 retuned. No cut on number of PVs anymore. Warning: different results than from DC04v2 stripping to be expected.
• HLT:
  • HltGeneric is always run. The explicit inclusion of $HLTGENERICROOT/options/HltGeneric.opts is not necessary anymore. Just do
     // Run HLT generic and HLT selections
#include "$HLTSELECTIONSROOT/options/HLTSelections.opts"
  • TrgParticleMaker now knows how to make protons and Bremsstrahlung-corrected electrons.

• CombineParticles (in Phys/PhysSelections): a new algorithm that allows to reconstruct any decay using only job options. Look at example option files in the Bs2JpsiPhi and Bu2LLK packages.

• PVIPFilterCriterion (in Phys/DaVinciTools) allows to filter particles according to their IP (or IP significance) to the reconstructed PVs. Works also for the pointing requirement for the B.

• ParticleMakerSeq (in Phys/DaVinciTools): A sequencer of particle makers. Allows to avoid PreLoadParticles.

Many small modifications in many packages.

The DaVinciUser practical example has been updated. Have a look.

This version compiles on Windows. Please use it and report any problems.

TDR data can be read but not all features are supported beside decay channel selections because of changes to LHCb packages (Event or Detector). Possible to perform analysis with Pool input.

Another major step towards DC'04. Based on Gaudi v14r5 and LHCb v15r9. Uses LoKi v2r4.

Now BTagging writes it's output to TES. All other Flavour Tagging code is obsolete and removed from DaVinci. The file IFlavourTagging.h is still there, but only to allow LoKi to compile. There's nothing behind it. Don't use it!

The L1Decision unit and the HLT are back. Trigger experts can use this version to optimize the trigger for DC04. Other users should not rely on the trigger results yet.

Many user selections for DC'04, following these guidelines, are made available. Don't hesitate to submit more code. DC'04 will start mid of May for DaVinci.

This version compiles on Windows. Please use it and report any problems.

TDR data can be read but not all features are supported beside decay channel selections because of changes to LHCb packages (Event or Detector). Possible to perform analysis with Pool input.

This version compiles on Windows. Please use it and report any problems.

TDR data can be read but not all features are supported beside decay channel selections because of changes to LHCb packages (Event or Detector). Possible to perform analysis with Pool input.

DaVinci v9r4 is an updated version fully compatible with TDR data. It is identical with DaVinci v9r3 except for some geometry-independent improvements introduced in versions v10 to v11r5. In particular there are several bug fixes in the DaVinci(MC)Tools and a new version of the B Tagging.

Also some new decay selections are introduced or updated.

Note that this is a branch, hence no developments based on this version are supported. Please base your changes on DaVinci v11r5 or later.

Apart from geometry changes, some backward-incompatible modifications in DaVinci v11 are not in this version. In particular DV v9r4 does not contain the new DVAlgorithm.h, hence selection following the guidelines will not run with DaVinci v9r4. Also the new track naming scheme is not applied.

People who would like to run the same algorithm with DaVinci v9r4 and DaVinci v11rX are encouraged to use precompiler flags in their requirement file

macro_append     cppflags " -DDVvnine " \
                 VisualC  " /DDVvnine "
and

#ifdef DVvnine

[...]

#endif

in their source code. Please leave the flags commented out in the requirements file you put in CVS.
