Jet-evolution in a medium via coherent emissions and scatterings

Description

Jets, i.e. collimated highly energetic sprays of quarks and gluons, are an excellent means to access the hot and dense medium of a quark gluon plasma (QGP), as they can travel through the medium and interact with it without thermalisation. Important contributions to in-medium jet-evolution come from scatterings off medium particles and emissions induced by these interactions - processes that can happen simultaneously, giving rise to the interference effects of coherent radiation. In this talk I present a numerical approach that describes the contribution to jet evolution from scatterings and coherent medium induced radiations. In particular, we found that the distributions of momentum components transverse to the jet axis broaden due to the medium in a way that significantly differs from a Gaussian distribution. We examine the effects of medium induced emissions and different types of scattering on transverse momentum broadening and find a clear ordering of contributions from emissions and scatterings.
