Plasma photoemission from string theory

Leading ’t Hooft coupling corrections to the photoemission rate of the planar limit of a strongly-coupled N = 4 SYM plasma are investigated using the gauge/string duality. We consider the full O(α ′3) type IIB string theory corrections to the supergravity action, including higher order terms with th...

description Leading ’t Hooft coupling corrections to the photoemission rate of the planar limit of a strongly-coupled N = 4 SYM plasma are investigated using the gauge/string duality. We consider the full O(α ′3) type IIB string theory corrections to the supergravity action, including higher order terms with the Ramond-Ramond five-form field strength. We extend our previous results presented in [1]. Photoemission rates depend on the ’t Hooft coupling, and their curves suggest an interpolating behaviour from strong towards weak coupling regimes. Their slopes at zero light-like momentum give the electrical conductivity as a function of the ’t Hooft coupling, in full agreement with our previous results of [2]. Furthermore, we also study the effect of corrections beyond the large N limit.
