RD: add BTohhGamma_GammaToEELL lines
- 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.
