Add Lambda EDM/MDM lines for Lb->LcX, Lc->LX decays

Mengzhen Wang requested to merge mengzhen_MEDM_bdecays_LambdaTT into master

This is a MR to add the hlt2 lines of several exclusive Lb->LcX, Lc->LX decays, with Lambda reconstructed using T tracks. These decays will be used to measure the spin processing of Lambda in LHCb magnet, which can tag its EDM and MDM.

Target on turbo lines without persistReco.

Test the rate using the template written by Ross in DaVinci!1019 (merged).

Rates of B meson control lines are high. Add prescale to make all the lines having a rate smaller than 100Hz. Following numbers are rates assuming prescale=1.0.

Efficiencies are tested using some local MC. Denominators are generated MC events WITHOUT any Lambda flight distance cuts.

Lb2LcPi, Lc2LambdaPi: 64./20000. = 0.32% (withUT), 83./20000 = 0.42 % (without UT). Only Truth-matched events contribute to the denominator
