Pions
Full Belle statistics - Same kinematic cuts of published pions:
-
pT dependence
z-pT multidimensional binning
z x sin2theta/(1+cos2theta)
pT x sin2theta/(1+cos2theta)
comparison T>0.8, T<0.8 no T cut
jet

To do/in progress
Done/almost done

• Need to investigate the differences in
pik before/now: bug or a real pid
effect?
