RD: add BTohhGamma_GammaToEELL lines

Fionn Caitlin Ros Bishop requested to merge fibishop-b2hhgee into master
  • HLT2 lines to select B->(Kpi,KK,pipi,pK)gamma for LL converted gamma + corresponding sprucing lines to run on output of Hlt2RD_BToHHGamma_GammaToEE once it is optimised
  • Adding brem to gamma_to_ee builder and tightening selections

Rates and efficiencies

Assuming input rate = 1.14MHz

MB input sample = 100K expected_2024_min_bias_hlt1_filtered

HLT2 Trubo lines (added lines)

Line Rate / Hz Signal efficiency / %
BdToKpPimGamma_GammaToEELL 23+/-16 0.3+/-0.1
BdToPipPimGamma_GammaToEELL 34+/-20 0.24+/-0.05
BsToKpKmGamma_GammaToEELL 34+/-20 0.27+/-0.05
LbToPpKmGamma_GammaToEELL 11+/-11 0.25+/-0.05

HLT2 inclusive full-stream lines (modified builders)

Line Old Rate / kHz New Rate / kHz
Hlt2RD_BToHHGamma_GammaToEE_InclDecision 0.89 +/- 0.1 0.25 +/- 0.05
Hlt2RD_BToHHHGamma_GammaToEE_InclDecision 0.62 +/- 0.08 0.18 +/- 0.05

Sprucing lines (added lines)

Rates not tested but very low rates expected: 100 Hz in case of full overlap between the new sprucing lines selection and the inclusive ones they sit on top of. Overlap may be low-ish, so 10Hz addition is more realistic. Quite well motivated: we need to validate the inclusive lines behaviour and these are the first sprucing lines on top of the converted photon radiative inclusive lines targeting converted photons.
