Description

We report on the first measurement of single muon from charm semileptonic decays at low transverse momentum (pT) in √(sNN)=200 GeV Au+Au collisions. Muon identification was obtained using the STAR time projection chamber in conjunction with a time-of-flight detector. The pT spectra of electron and muon from charm semileptonic decays are presented. The measured D→μ+X at pT<0.25 GeV/c greatly constrains the charm total cross section. The charm differential cross section dσcc/dy is found to be consistent with the number of binary collision scaling. (orig.)
