ρ events
Generated 100000 events with genr8
Require pπ+π-, each with tracking CL>0.001
Use default PID algorithm
4C kinematic fit (nothing missing)
Missing mass squared for the reaction γp->pπ-π+. Red histogram is after a 0.01 CL cut on the result of kinematic fitting
b1π events
Generated 100000 events with genr8
Require p2π+2π-, each with tracking CL>0.001
Use default PID algorithm
1C kinematic fit (missing π0)
Missing mass squared for the reaction γp->p2π+π-(X). Red histogram is after cutting on CL from kinematic fitting at 0.01.
Black histogram uses momenta from tracking reconstruction; red histogram uses refined momenta returned by kinematic fitting code
