  Reliable predictions for jet quenching in ultra-relativistic heavy ion
collisions require accurate computation of radiative energy loss. While all
available energy loss calculations assume 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 generalized the
dynamical energy loss formalism, to consistently include a possibility for
existence of non-zero magnetic screening. We show that this generalization
indicates a fundamental constraint on electric to magnetic mass ratio, which
appears to be supported by lattice QCD simulations. Jet suppression patterns,
obtained from this newly developed generalization, show reasonable agreement
with the available RHIC and LHC measurements.
