摘要：

We extend the computational framework of [1] to analysis of shear and bulk viscosities in generic strongly coupled holographic Gauss -Bonnet gauge theories. The finite Gauss -Bonnet coupling constant encodes holographic plasma with non -equal central charges c # a at the ultraviolet fixed point. In a simple model we discuss transport coefficients within the causality window - 1 2 <= c - a c <= 12 of the theory.
