Improved determination of the sample composition of dimuon events produced in {\boldmath $p\bar{p}$} collisions at {\boldmath $\sqrt{s}=1.96$} TeV

CDF Collaboration

We use a new method to estimate with 5% accuracy the contribution of pion and kaon in-flight-decays to the dimuon data set acquired with the CDF detector. Based on this improved es…
