Title: Universal magnetoresponse in QCD and $$ \mathcal{N}=4 $$ SYM

Abstract

Using recent lattice data on the thermodynamics of QCD in the presence of a background magnetic field, we show that the ratio of transverse to longitudinal pressure exhibits, to good accuracy, a simple scaling behavior over a wide range of temperature and magnetic field, essentially depending only on the ratio T/√B. We compare this QCD response to the corresponding magnetoresponse in maximally supersymmetric Yang Mills theory. Given suitable calibrations defining the comparison, we find excellent agreement. Furthermore, this may be viewed as a further test of the applicability of holographic models for hot QCD.
