Abstract

We studied the evolution of jets within a medium that contains both,\ntransverse kicks as well as medium induced coherent radiation. In this\nframework parton branching occurs simultaneously to scatterings within the\nmedium, leading to the interference effects that reproduce the well known\nBDMPS-Z emission rates and sizeable transverse momentum broadening. We examined\nthe relative importances of transverse momentum broadening from the coherent\nsplittings and different types of in-medium scatterings and found a clear\nhierarchy of the influences from different scattering effects and deflections\nduring branchings.\n
