B2 pp pmhh dv

Youhua Yang requested to merge B2PpPmhh_DV into bnoc_run3

Found bug on the decay distance of mother particle of B. Previously, succeed from run2 stripping, using B_MIPDV which corresponding to Thor function MINIP. it was decay distance of B0 so the value is small. But wrong functor MINIPCHI2 was used, which decrease the efficiency and rate dramatically. Now it is changed back.

And Now also modify the cut of final state same as B2hhhh like pid, min_two(three)body_mva, and doca. The mass range is adjusted too.

rate(without ut):

pipi: 0.342
Kpi: 0.228
KK:0.171

Efficiency (without ut):

B->pppipi: (6.3 +- 0.4)%
B->ppKpi: ( 8.0 +- 0.4)%
B->ppKK: (9.1 +- 0.9)%
