3 Analysis Strategy  Plans:  (1) analysis of decay pions and decay vertex  We are working on Opeartor #4.  For delatM= 200, 500, 1000 MeV  - pt(pi+), pt(pi-), pt(pi+pi-), pt(pi+)/pt(pi-)  - opening angle of pi+ and pi-  - decay vertex R=sqrt(x*x+y*y), z, 2Dplot(R vs z)  - pt(chi+chi*) at IP (interaction point)  - pt(chichi) ?  (2) test pythia for deltaM=3GeV (and 2Gev).  Mass(chi*) 503.0 GeV M(chi) = 500 GeV chi* -> chi + u + ubar  Does Pythia produce hadrons for those u and ubar?  If hadronization is done in pythia, check the following.  - multiplicity of hadrons  - pt of each hadrons  - decay points.
