Scaling of the charm cross-section and modification of charm $p_T$ spectra at RHIC

Abstract

Charm production from the direct reconstruction of $D^0$ ($D^0\to K\pi$ up to 2 GeV/$c$) and indirect lepton measurements via charm semileptonic decays ($c\to e+X$ at 0.9\textless$p_T$\textless5.0 GeV/$c$ and $c\to \mu +X$ at 0.17\textless$p_T$\textless0.25 GeV/$c$) at $\sqrt{s_{{}_{NN}}}=200$ GeV Au+Au collisions are analyzed. The transverse momentum ($p_T$) spectra and the nuclear modification factors for $D^0$ and for leptons from heavy flavor decays is presented. Scaling of charm cross-section with number of binary collisions at $\sqrt{s_{{}_{NN}}}=200$ GeV from d+Au to Au+Au collisions is reported.
