Strangeness production with "massive" gluons

We present a perturbative calculation of strange-quark production by the processes $g\to s+\overline{s}$, $g+g\to s+\overline{s}$, and $q+\overline{q}\to s+\overline{s}$ in a quark-gluon plasma containing gluons that are effectively "massive" due to medium effects. We consider only transverse polarizations of the gluons. We find that for a gluon mass beyond 300 MeV the one-gluon decay dominates, and that there is an enhancement of $s\overline{s}$ production from massive gluons compared with the massless case.
