Summary

First look at 25k Xicc+ MC,
Min daughter IP chi^2 wrt PV,
Last week looked at IP,
Look at IP Chi^2 instead,
Doesn’t seem useful either.
Minimum Pt [MeV] and Min daughter IP Chi^2 values are listed.
Summary of variables:
Useful Variable, Cut type, Loose, Tight,
Pt greater than, Mother, 3.5GeV, 4.5GeV,
End Vertex Chi^2 less than, Mother, 5.5, 3,
DIRA greater than, Mother, 0.999, 0.9996,
DOCA less than, Combina1on, 1.25, 0.75,
PIDp greater than, Daughter, 15, 30,
PIDK greater than, Daughter, 5, 15,
All daughter track Chi^2 less than, Daughter, 3.5, 2,
Daughter track Ghost Probability less than, Daughter, 0.5, 0.5.
Cuts providing no DiscriminaMinimum fdpv and fdpv Chi^2,
Minimum (greatest daughter IP and IP Chi^2).
25k events generated by Feng,
Lambda_c Selec1on and Xicc+ Selec1on criteria are listed.
Xicc+ MC: 25k events, around 500 signal events, naive 2% efficiency.
htemp: Entries 14280, Mean 65.92, RMS 16.96.
