Reliable predictions for jet quenching in ultra-relativistic heavy ion
collisions require accurate computation of radiative energy loss. With this
goal, an energy loss formalism in a realistic finite size dynamical QCD medium
was recently developed. While this formalism assumes zero magnetic mass - in
accordance with the one-loop perturbative calculations - different
non-perturbative approaches report a non-zero magnetic mass at RHIC and LHC. We
here generalize the energy loss to consistently include a possibility for
existence of non-zero magnetic screening. We also present how the inclusion of
finite magnetic mass changes the energy loss results. Our analysis indicates a
fundamental constraint on magnetic to electric mass ratio.Comment: 4 pages, 2 figure
