Run3-B2psiX_merged
This is a AP to try merging all these decays into one root file:
(1) Lambda_b -> J/psi(2mumu) p K-;
(2) Lambda_b -> J/psi(2mumu) p pi-;
(3) Bp -> J/psi(2mumu) K_S(2pipi) pi+;(LL and DD)
(4) Xi_b -> J/psi(2mumu) Lambda(2ppi-) K;(LL and DD)
(5) Bp -> J/psi(2mumu) p Lambda~(2ppi+); (LL and DD)
(6) Bp -> J/psi(2mumu) phi(1020) K+;
(7) B -> J/psi(2mumu) p p
(8) B -> J/psi(2mumu) p pi-
