Heavy quark energy loss and D-Mesons at RHIC and LHC energies

Understand

We obtain the radiative energy loss of a heavy quark in a deconfined medium due to radiation of gluons off them using a recently derived generalised gluon emission spectrum.

• We find that the heavy flavour loses energy almost in a similar fashion like light quarks through this process.
• With this, we further analyse the nuclear modification factor for D-meson at LHC and RHIC energies.
• In particular, the obtained result is found to be in close agreement with the most recent data from ALICE collaboration at 2.76 ATeV Pb-Pb collisions.
