摘要
Deep inelastic scattering off the strongly coupled N = 4 supersymmetric Yang-Mills plasma at finite temperature can be computed within the AdS/CFT correspondence, with results which are suggestive of a parton picture for the plasma. Via successive branchings, essentially all partons cascade down to very small values of the longitudinal momentum fraction x and to transverse momenta smaller than the saturation momentum Q(s) similar to T/x. This scale Q(s) controls the plasma interactions with a hard probe, in particular, the jet energy loss and transverse momentum broadening.
