Description
The charm quarks are expected to be produced at the
initial fusion of the ultrarelativistic
heavy-ion collisions. Just after the production, they will propagate
through the Quark Gluon Plasma (QGP) and will loose energy by
colliding with quarks and gluons and radiating gluons.
We calculate the nuclear modification
factor $R_{AA}$ of charm
quarks, produced from the initial fusion of partons
in a nuclear collision, at $\sqrt{s_{NN}}$=2.76 TeV Pb-Pb collision at LHC at more forward rapidities .
At the
relativistic
heavy-ion collisions, nuclear shadowing effect will also play an important role. In this study, we take in to account
the effect of collisional and radiative energy loss of the charm
quarks
while passing through the QGP and also the gluon shadowing effect while calculating $R_{AA}$.
We have considered some of the important
formalisms available in the literature for the calculation of medium-induced radiative and collisional
energy loss. The shadowing effect is introduced by using EKS 98
parameterization for structure functions.
