1) NPE Updates by Kunsu - Slides
- HIJING Reverse of DCA_XY shows only a small improvement over non-mirrored version for reproducing data shape
- Change fit parameters from R_c & R_b to R_b & R_(b+c)
- When allowed to fit freely, see ~60% contribution of pion distribution. This is clearly too much. Looks like pion is "eating" the contributions from Dalitz and Conversion e due to similar shapes at small DCA. Suggest trying to fit in a side region to see if there is discimination power in the tail for these distributions. If not, we will need to find some way to apply constraints. Applying a flat 20% contribution limit on pion results in a poor fit.
- Using PHE from HIJING, fit errors bars larger at high pT where we expect them to be smaller... likely due lack of shape matching for DCAXY in PHE from HIJING to data.
