We study high mass dilepton production from gluon-induced processes, $g q \to q \gamma^*$, $g \bar q \to \bar q \gamma^*$, and $g g \to q \bar q \gamma^*$, in a thermally equilibrated but chemically under-saturated partonic matter that is…
We calculate leading-order dilepton yields from a quark-gluon plasma which has a time-dependent anisotropy in momentum space. Such anisotropies can arise during the earliest stages of quark-gluon plasma evolution due to the rapid…
