B2OC: Tuning of the DToKsHH builder (shifters please ignore)
Cut tuning to solve the max. combination issue with the D0ToKsHH builder.
- require IPCHI2 > 6 for all pions or kaons from D (this will affect all lines with
D -> Ks h h
) - tighten PID cut for BuToD0H, D0ToKsHH lines: was
pi_pidk_max=20, k_pidk_min=-10
, nowpi_pidk_max=10, k_pidk_min=-5
(PIDK cut of kaon equals to the default value) - remove MVA cut of BuToD0H, D0ToKsHH lines. (now a cut of
0.2
is applied by default)
