Darkboson rd lines

Martin Andersson requested to merge darkboson_rd_lines into master

Rare decay exclusive line for B0 -> K*0 Darkboson and B+ -> K+ DarkBoson, where the dark boson can be detached and decays to dileptons: mumu, ee, e mu.

Only including long leptons here. Will make another MR for down tracks, as there were issues with efficiencies and rates.

Tested on B0 -> K* DarkBoson(->mumu) MC, with Dark boson properties: m=2500MeV, t=10 ps and t=100 ps. ee and mue efficiencies are also from mumu MC, with PIDe turned off.

Efficiencies t=10ps:

eff_pid3_dira9999_mmin4500_fd121_t10

Updated PIDmu, ~1000 events:

Line: Hlt2RD_BdToKstLLP_LLPToMuMu_LineDecision Efficiency: 0.183 +/- 0.017

Efficiencies t=100ps:

eff_pid3_dira9999_mmin4500_fd121_t100

Updated PIDmu, ~1000 events:

Line: Hlt2RD_BdToKstLLP_LLPToMuMu_LineDecision Efficiency: 0.187 +/- 0.038

Rates: rates_pid3_dira9999_mmin4500_fd121
