HQ Collisional energy loss in a magnetized medium

Understand

We study the effect of the magnetic field on the collisional energy loss of heavy quark (HQ) moving in a magnetized thermal partonic medium.

• This is investigated in the strong field approximation where the lowest Landau level (LLL) becomes relevant.
• We work in the limit $g\sqrt{eB}\ll T\ll \sqrt{eB}$ which is relevant for heavy ion collisions.
• Effects of the magnetic field are incorporated through the resummed gluon propagator in which the dominant contribution arises from the quark loop.
