In this study, we propose a system of evolution equations to describe the in-medium time-evolution of quark and gluon fragmentation functions. We solve this system using Monte Carlo methods and quantify the obtained solutions in terms of average transverse momentum and energy in a cone. Our results demonstrate different behaviors of quark and gluon initiated final-state radiation, with less energy observed in a cone for gluon-initiated processes, indicating a more collimated quark jet.
We propose a system of evolution equations that describe in-medium time-evolution of transverse-momentum-dependent quark and gluon fragmentation functions. Furthermore, we solve this system of equations using Monte Carlo methods. We then quantify the obtained solutions in terms of a few characteristic features, namely the average transverse momentum and energy contained in a cone, which allow us to see different behaviour of quark and gluon initiated final-state radiation. In particular, the later allows us to conclude that in the gluon-initiated processes there is less energy in a cone, so that the quark jet is more collimated.
