Description

"I am going present solutions of evolution equations for inclusive
distribution of gluons as produced by jet traversing quark-gluon
plasma. The the original equation is reformulated in such a form that
the virtual and unresolved-real emissions as well as unresolved
collisions with medium are resummed in a Sudakov-type form factor. The
resulting integral equations are then solved most efficiently with use
of newly developed Markov Chain Monte Carlo algorithms implemented in
a dedicated program called MINCAS. Their results for a gluon energy
density are compared with an analytical solution and a differential
numerical method. Some results for gluon transverse-momentum
distributions are also presented. They exhibit interesting patterns
not discussed so far in the literature, in particular a departure from
the Gaussian behavior - which does not happen in approximate
analytical solutions.
