Optimize selections in open-charm and charged hadron builders in BandQ area
In a recent MR !2132 (merged) , authors use the standard particle combiners in bandq
area to build decays of Xib -> J/psi hhh and bbaryon -> Lc Ds h(h) , whose rate should not be too high. However, the result rate is about 500Hz level. It's a hint that we should tighten the default selections of some standard B&Q particles, or provide some tighten versions to help line authors tune the rate.
We can start from comparing with Charm, B2OC and SL combiners. @ipolyako already made the comparison of D-meson selections: see here.
