An elementary stringy estimate of transport coefficients of large temperature QCD
arXiv:1006.4634 · doi:10.1007/JHEP08(2010)128
Abstract
Modeling QCD at large temperature with a simple holographic five dimensional theory encoding minimal breaking of conformality, allows for the calculation of all the transport coefficients, up to second order, in terms of a single parameter. In particular, the shear and bulk relaxation times are provided. The result follows by deforming the AdS background with a scalar dual to a marginally relevant operator, at leading order in the deformation parameter.
