  We focus on evaluating transport coefficients like drag and diffusion of
heavy quarks (HQ) passing through Quark Gluon Plasma using perturbative QCD
(pQCD). Experimental observable like nuclear suppression factor (RAA) of HQ is
evaluated for both zero and non-zero baryonic chemical potential ({\mu}_B)
scenarios using Fokker- Planck equation. Theoretical estimates of RAA are
contrasted with experiments.
