TL;DR

This paper explores the connection between the strongly coupled quark-gluon plasma and holographic conformal field theories by calculating higher curvature corrections to transport coefficients in the dual gravity framework.

Contribution

It provides a detailed calculation of second-order hydrodynamic transport coefficient corrections from higher curvature terms in holography, clarifying their application to sQGP comparisons.

Findings

Higher curvature terms modify transport coefficients in holographic models.

Results help refine the quantitative comparison between sQGP and holographic CFTs.

Clarification on the consistent application of these corrections in sQGP studies.

Abstract

We examine the proposal to make quantitative comparisons between the strongly coupled quark-gluon plasma and holographic descriptions of conformal field theory. In this note, we calculate corrections to certain transport coefficients appearing in second-order hydrodynamics from higher curvature terms to the dual gravity theory. We also clarify how these results might be consistently applied in comparisons with the sQGP.
