The main issue is related to the mistag (cannot be fitted)

B2hh data production

Starting up

  • First of all get latest DaVinci
  • Compile
  • Setup ganga using GangaEnv
  • Submit jobs using job/DaVinci_ganga.py properly modified
  • Get grid data cards from bkk page
    • DC06 data (30/05/08) and instructions can be found here

Submitted jobs

Several Grid jobs have been submitted to create the microDST(s). Data can be found under the /castor/cern.ch/grid/lhcb/user/a/asarti/ dir.

ganga job type dirac jobnum
1390 1st half Bdpipi 574039 -> 068
1391 2nd half Bdpipi  
1392 BsKK 574081
1393 BsKpi 574083 -> 84
1394 1st half BdKpi 574088 -> 99
1395 2nd half BdKpi 574109 -> 23

DST

 
// Include rDST objects
#include "$STDOPTS/rDstContent.opts"

// If DST comes from stripping ETC, add also selection results
DstWriter.Preload = false;
DstWriter.ItemList += {"/Event/Phys#99"};
DSTOR.ItemList  = @DstWriter.ItemList ;
DstWriter.OptItemList = {};

#include "$STDOPTS/MCDstContent.opts" // remove for real data or when running on rDST

ApplicationMgr.OutStream += { "DSTOR" } ;
DSTOR.RequireAlgs  = { "SelB2HH" };
DSTOR.OutputLevel = 1;
DSTOR.Output = "DATAFILE='prova.dst' TYP='POOL_ROOTTREE' OPT='RECREATE'";

microDST

Those instructions can be used to create microDST.

 
#include "$MICRODSTALGORITHMROOT/options/microDST.opt"

SeqDC06selBs2Jpsi2MuMu_Phi2KK.Members   += {"CreateMicroDSTAlg/microDST"};
SeqDC06selBs2Jpsi2MuMu_Phi2KK.Members   += {"CreateMicroDSTMCAlg/microDSTMC"};
SeqDC06selBs2Jpsi2MuMu_Phi2KK.Members   += {"CopyMCParticles"};

microDST.PhysDesktop.InputLocations      = {"/Event/Phys/DC06selBs2Jpsi2MuMu_Phi2KK"};
microDST.OutputLevel                     = 4;

microDSTMC.PhysDesktop.InputLocations    = {"/Event/Phys/DC06selBs2Jpsi2MuMu_Phi2KK"};
microDSTMC.OutputLevel                   = 4;

CopyMCParticles.InputLocation = "MC/Particles";
CopyMCParticles.OutputLevel              = 4;

DSTStream.Output = "DATAFILE='$PATHTOOUTPUT/Filename.micro.dst'
TYP='POOL_ROOTTREE' OPT='REC'";

When running against Stripped you should add somethingmore:

 
EventSelector.Input   = {
"COLLECTION='TagCreator/1'
DATAFILE='PFN:castor:/castor/PATHTOINPUT/INPUT_00002042_00000001_2.root
' TYP='POOL_ROOT'"
};

ApplicationMgr.ExtSvc  += { "TagCollectionSvc/EvtTupleSvc" };
FileCatalog.Catalogs  = { "xmlcatalog_file:$PATHTOINPUT/INPUT.xml" } ;
