New decfiles with optimised cuts for B -> Jpsi Eta(') decays

Maximilien Chefdeville requested to merge chefdevi/jpsietas2pipix0 into master

Added kinematics and acceptance cuts to several existing decfiles, incremented event type accordingly. Efficiencies are calculated with GaussJobs with 1000 events (absolute error ~ 0.5-1%), details in decfiles_eff_summary.txt.

  • Modif of Bs_Jpsieta,mm,pipipi=DecProdCut.dec 13144401 (eff=15.4%) (11144432 for Bd):
    -> Bs_Jpsieta,mm,pipipi=TightCut,LowPt.dec 13144407 (eff=6.8%)
    -> Bd_Jpsieta,mm,pipipi=TightCut,LowPt.dec 11144433 (eff=6.6%)

  • Modif of Bs_Jpsietap,mm,etapipi=DecProdCut.dec 13144411 (eff=15.0%) (11144460 for Bd):
    -> Bs_Jpsietap,mm,etapipi=TightCut,LowPt.dec 13144415 (eff=8.9%)
    -> Bd_Jpsietap,mm,etapipi=TightCut,LowPt.dec 11144461 (eff=8.9%)

  • Modif of Bs_Jpsieta,mm,pipig=DecProdCut.dec 13144220 (eff=15.4%) (11144220 for Bd):
    -> Bs_Jpsieta,mm,pipig=TightCut,LowPt.dec 13144221 (eff=10.5%)
    -> Bd_Jpsieta,mm,pipig=TightCut,LowPt.dec 11144221 (eff=10.7%)

  • Modif of Bs_Jpsietap,mm,rhog=DecProdCut.dec 13144201 (eff=15.2%) (11144210 for Bd):
    -> Bs_Jpsietap,mm,rhog=TightCut,LowPt.dec 13144205 (eff=10.5%)
    -> Bd_Jpsietap,mm,rhog=TightCut,LowPt.dec 11144211 (eff=10.3%)

Purity increase with gen-cuts depends on the decay kinematic and varies from 2.3 for low PHSP modes to 1.5 for modes with higher PT final state particles.

We also incorporate to this merge request three decfiles (13142405, 11142213, 13142215) from !1075 (closed). The latter request will be closed.
