Description |
The heavy quarks (HQs) are considered to be effective probes to study the evolution of the QGP. We study the dynamics of HQs in a hot QCD medium with a time-correlated noise, $\eta$. We have introduced the effect of memory through $\eta$ and the dissipative force in the Generalized Langevin equation (GLV). We supposed that the time correlations of the colored noise decay exponentially with time, called the memory time, $\tau$. We have explored the effect of non-zero values of $\tau$ on the nuclear modification factor, $R_{AA}$, and transverse momentum broadening, $\sigma_p$ of the HQs within the QGP medium. We find that overall memory slows down the momentum evolution of heavy quarks: in fact, transverse momentum broadening and the formation of $R_{AA}$are slowed down by memory. larger. |
