Description
We develop an effective field theory (EFT) formalism to study the interaction of a heavy quark with the medium. All the operators consistent with the underlying symmetry and power counting in $l_{\text{hydro}}$, the hydrodynamic length scale, are written down. Using these EFT principles leads to only few general operators which are organized in terms of order of importance. The Wilson coefficients for these operators, which provides the coupling of the heavy quark to the hydrodynamic medium, can then be estimated from experiments directly in the non-perturbative regime or obtained from an ultraviolet theory in a perturbative regime by matching to it.
