Title: Gluon bremsstrahlung in finite media beyond multiple soft scattering approximation

Abstract

We revisit the calculation of the medium-induced gluon spectrum in a nite QCD medium and develop a new approach that goes beyond multiple soft scattering approximation. We show by expanding around the harmonic oscillator that the rst two orders encompass the two known analytic limits: single hard and multiple soft scattering regimes, valid at high and low frequencies, respectively. Finally, we investigate the sensitivity of our results to the infrared and observe that for large media the spectrum is weakly dependent on the infrared medium scale.
