Magnetic and electric contributions to the energy loss in a dynamical QCD medium

Understand

The computation of radiative energy loss in a finite size QCD medium with dynamical constituents is a key ingredient for obtaining reliable predictions for jet quenching in ultra-relativistic heavy ion collisions.

• It was previously shown that energy loss in dynamical QCD medium is significantly higher compared to static QCD medium.
• To understand this difference, we here analyze magnetic and electric contributions to energy loss in dynamical QCD medium.
• We find that the significantly higher energy loss in the dynamical case is entirely due to appearance of magnetic contribution in the dynamical medium.
