Fully quantum treatment of the Landau--Pomeranchuk--Migdal effect in QED and QCD
read the original abstract
For the first time a rigorous quantum treatment of the Landau-Pomeranchuk-Migdal effect in QED and QCD is given. The rate of photon (gluon) radiation by an electron (quark) in medium is expressed through the Green's function of a two-dimensional Schr\"odinger equation with an imaginary potential. In QED this potential is proportional to the dipole cross section for scattering of $e^{+}e^{-}$ pair off an atom, in QCD it is proportional to the cross section of interaction with color centre of the color singlet quark-antiquark-gluon system.

Full energy fraction and angular dependence of medium-induced splittings in the large-$N_c$ limit
In large-Nc and harmonic oscillator limits, medium-induced splittings are computed analytically double-differential in z and θ, with an improved semi-hard approximation validated for high-energy partons.

Energy Loss of a Heavy Quark in a Collisional Quark-Gluon Plasma
Including thermal parton collisions via the BGK kernel increases the collisional energy loss of a heavy quark in QGP by ~8% at large velocities for α_s=0.3 compared to the collisionless limit.
