“…Furthermore it will be interesting to see the signature of the rescattering during branching in some final state. One of the possibilities is to study decorelations of jets following [40].…”

We study evolution equations describing jet propagation through quark-gluon plasma (QGP). In particular we investigate the contribution of momentum transfer during branching and find that such a contribution is sizeable. Furthermore, we study various approximations, such as the Gaussian approximation and the diffusive approximation to the jet-broadening term. We notice that in order to reproduce the BDIM equation (without the momentum transfer in the branching) the diffusive approximation requires a very large value of the jet-quenching parameter $$ \hat{q} $$ q ̂ .

“…( 2) and ( 6) can be written as integral equations, which can be solved numerically via a Monte-Carlo algorithm, as it was done by the MINCAS-program [2]. In our approach [7] we obtained the four momenta of the gluons produced in the hard collisions via the KATIE-program and then the changes in gluon momenta due to in-medium evolution via the MINCAS-program. We parametrize the medium as follows:q = 0.29 GeV 2 /fm, n = 0.08 GeV 3 , m D = 0.61 GeV.…”

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 the jets produced in hard binary collisions and their interactions with a tentative medium. These jets were obtained numerically from the Monte-Carlo simulations of hard collisions using the KATIE-algorithm [1], where parton momenta within the colliding nucleons were describe by means of unintegrated parton distribution functions (uPDF). We evolved these jets within a medium that contains both, transverse kicks (yielding a broadening in momentum transvers to the jet-axis) as well as medium induced radiation within the MINCAS-algorithm [2] following the works of [3,4]. We produce qualitative results for the decorrelation of dijets. In particular, we study deviations from a transverse momentum broadening that follows a Gaussian distribution.
