Productions of Heavy Flavored Mesons in Relativistic Heavy Ion Collisions in the Recombination Model

Abstract

We get the distributions of shower partons initiated by heavy quarks $c$ and $b$ by studying the fragmentation functions in the framework of the recombination model. The transverse momentum spectra of heavy flavored mesons are predicted with these distributions. We find that the contribution from the recombination of thermal-shower partons is an important part in the total spectrum for the mesons. We predict the heavy flavored meson productions for different centralities with the heavy quark fugacities fitted by the experimental data of $J/\psi$ transverse momentum spectra in Au+Au collisions.
