For all dataTrees in tagmix except mass_dataTree, it only has fill and dmass.
| fill | Index for B0s in event (we might reconstruct 2 unique B0->D*lnu
in a single event, but this number is almost always 1) |
| deltat | This is time between B0 decays |
| dterr | This is error on dt calculated by VtxTagBtaSelFit |
| dtTrue | MC truth for dt |
| dt_res | (dt - dt_mctruth) - only for MC and for events with B0s,
otherwise -999 |
| Treco,TrecoMC | reco z position converted to time |
| Ttag,TtagMC | tag z position converted to time |
| Tcharm | z position of D0 or D+/- from tag side closest to Ttag |
| pull | dt_res/dterr |
| tag | -1 = the event is mixed (i.e. both decay as B0s or B0bars)
+1 = the event is unmixed |
| MCtag | MC version of tag |
| leptID | MC lepton id:
1 = electron 2 = muon 3 = fake |
| mcb1 | MC index of first B in decay (charged or neutral) |
| mcb2 | MC index of second B in decay (charged or neutral) |
| mcz1 | MC z position of first B in decay |
| mcz2 | MC z position of second B in decay |
| ztag | Tagside z position from VtxTagBtaSelFit |
| zreco | Recoside z positon |
| mcztag | MC z position of tag side (only works when dstarlnu=1) |
| mczreco | MC z position of reco side (only works when dstarlnu=1) |
| dmass | This is the D* - D0 mass difference |
| dmass_unfit | D*-D0 mass difference without refitting |
| dmasserr | Error on dmass |
| dstarlnu | 0 = no B->D*lnu in event
1 = yes B->D*lnu in event |
| doubledstar | 0 = Only one or neither side decayed as B0->D*lnu
1 = Both sides decayed as B0->D*lnu |
| doublecharm | 0 = No charm vertex (D0 or D+/-) found on tag side
1 = One charm vertex found tag side 2 = Two charm vertices found tag side |
| chargedb | 0 = Y4S -> B0 B0bar
1 = Y4S -> B+ B- |
| cosDsl | Angle between reco D* and reco lepton |
| cosBY | Angle between B and D*l assuming B0->D*lnu |
| cosBYf | Same as costhetaby except using flip leptons |
| slowpiPt | Pt of reco slow pion |
| maxtagp | P of highest momentum particle used in the tag vertex |
| numtagused | Number of particles used in the tag vertex |
| leptonmomentum | Momentum of reco lepton |
| dstarmomentum | Momentum of reco dstar |
| lepton_cat | 1 = electron
2 = muon 3 = fake |
| sample_cat | 0 = No sample - falls outside all samples
1 = signal 2 = combinatoric sideband 3 = fake lepton sample 4 = Uncoorelated lepton sample |
| D0_cat | 0 = no D0 decay found
1 = D0->kpi 2 = D0->k3pi 3 = D0->kpipi0 4 = D0->kspipi |
| tagCatGrp | 1 = lepton tag
2 = kaon tag 3 = net1 tag 4 = net2 tag 5 = no tagging category |
| tagside_flavor | Tag side flavor determined by NOT or Nettagger
+1 = nettagger > 0.2
|
| angleCor | 1 = signal sample
2 = flip sample 3 = Neither, not used (but must be discarded) |
| bgType | MC truth about the event
0 = good signal
|
| Dstarcuts | 0 = no cuts
1 = pass D0 vertex cut 2 = pass D0 mass cut 3 = pass Kaon ID and Dalitz cut 4 = pass D* cuts 5 = pass lepton p* cut, good or fake l and D*l vertex cut 6 = dt, dterr cuts 7 = thrust cut 8 = Angular cuts in signal region 9 = pass Vtight lepton ID 10 = tighter dterr, ntrack tagside cut |
| D0mass | Mass of D0 from Dstar |
| probDstarl,
probDstar, probD0 |
prob of vertex for each candidate |
| dmass_sample_cat | Same as above except no mass window cut,
