Drag and diffusion co-efficients of heavy quarks in hard thermal loop
approximations    [PDF]

Surasree Mazumder, Trambak Bhattacharyya, Jan-e Alam

The drag and diffusion coefficients of heavy quarks propagating through quark gluon plasma (QGP) have been evaluated within the ambit of thermal field theory in Hard Thermal Loop (HTL) approximations. It is observed that the magnitudes of both the transport coefficients are changed significantly from their values obtained when the $t$ channel divergence is shielded simply by Debye mass. The implications of this changes in the transport coefficients on the heavy ion phenomenology have been discussed.
