The $p_T$ Distribution of $J/\psi$ in QGP

Abstract

We consider the contributions of both color-singlet and octet $c\bar{c}$ bound states for studying the suppression of $J/\psi$ production in quark gluon plasma (QGP) and have found that the existence of the color-octet $c\bar{c}$ may cause the $p_T-$distribution of $J/\psi$ a decrease with $p_T$ after a critical value $(p_T{)}_{max}$, which is quite different from the behavior in Hadronic Matter (HM).
