Abstract
We report on the measurement of D meson production from the analysis of their hadronic (D0 → Kπ) and semileptonic (D → μ + X, D → e + X) decays in GeV Au+Au collisions. The transverse momentum (pT) spectra and the nuclear modification factors for D0 and for electron/muonThe word ‘muon’ refers to μ+/μ−, ‘electron’ refers to electron/positron throughout this article. from charm semileptonic decays will be presented. The differential cross section dσ/dy is found to be consistent with the number of binary scaling. The blast-wave fit suggests that the charm hadron freeze out earlier than other light flavour hadrons.
