Description
Heavy ion collisions at high energies can be used as an interesting way to recreate and study the medium of the quark-gluon plasma (QGP).
We particularly investigate how jets produced in hard binary collisions evolve within a tentative medium and in particular how the jet-particle momentum components $k_T$ orthogonal to the jet
axis are affected.
We evolved the jets within a medium that contains both, transverse kicks
as well as medium induced coherent radiation within the MINCAS-algorithm [1] following the works of [2,3].
In this framework parton branching occurs simultaneously to scatterings within the medium, leading to the interference effects that reproduce the well known BDMPS-Z emission rates and sizeable $k_T$ broadening.
It is, thus, interesting to study the relative importances of $k_T$ broadening from the coherent splittings and different types of in-medium scatterings.
We find a clear hierarchy of the influences from different scattering effects and deflections during branchings:
While scattering still yields the largest contributions to broadening, the branching effects are comparable in size.
We also observed that the $k_T$ distributions in our results differ considerably from a Gaussian distribution in transverse momentum.
