WIP Loosening lower B mass cut in B2XMuMu + using VeryLooseKsLL instead of LooseKsLL in S21r0p2

Closed WIP Loosening lower B mass cut in B2XMuMu + using VeryLooseKsLL instead of LooseKsLL in S21r0p2
Renata-S21r0p2-B2XMuMu-BmassLoose into stripping21-patches
Closed Renata Kopecna requested to merge Renata-S21r0p2-B2XMuMu-BmassLoose into stripping21-patches

Loosening the cut will improve the control over the tails in the K*->K+pi0 channel. Has already been done in S28 (see !629 (merged) (diffs))

The StdVeryLooseKsLL container increases the number of KsLL candidates by roughly 50%.

Rates stay well below 0.5% (see below)
