B2ll lines and B2llgamma (!1094) · Merge requests · LHCb / Moore

Merged Titus Mombaecher requested to merge tmombach_B2ll_lines into master 3 years ago

B2mumu (also same-sign), B2hh, B2ee (also same-sign), B2emu (also same-sign) and the corresponding B2llgamma lines. The mass windows are large enough to cover B0 and Bs decays (in spite of the decay descriptor being Bs)

B2mumu and B2hh use Flavour Tagging

Lines inspired by Run 2 Stripping with the aim to allow lower lifetimes (favourable for B2hh and B2mumu TD-CPV studies). Efficiency studied with a B2mumu sample (without HLT1 filter, denominator is CanRecoChildren):

Line:    Bs_Hlt2RD_BToHH_LineDecisionTOS               Efficiency:     0.621 +/- 0.019
Line:    Bs_Hlt2RD_BToMuMu_LineDecisionTOS             Efficiency:     0.525 +/- 0.020

For the radiative lines (that have zero rates) I have tested on the standard minbias sample with a significantly loosened BIPCHI2 (<1000)

So the selection does work. But I was not able to run over the (ancient) B2mumugamma sample.
