A bstractWe revisit the determination of the two-loop spectral function in the shear channel of hot Yang-Mills theory. Correcting a technical error in an earlier computation is seen to improve the infrared behavior of the quantity significantly, while a partial Hard Thermal Loop resummation is seen to have only a very minor numerical effect on the result. These facts make it possible to straightforwardly apply the spectral function to the corresponding imaginary time correlator and the shear… 
Transport Peak in the Thermal Spectral Function of N=4 Supersymmetric Yang-Mills Plasma at Intermediate Coupling.
The emergence of a separation of scales in the analytic structure of the thermal correlator associated with two types of characteristic relaxation modes is observed and may be described as a transport peak typically found in perturbative, weakly interacting thermal field theories.

A lattice Monte Carlo calculation of the trace-anomaly two-point function at finite temperature in the SU(3) gauge theory is performed and the long distance properties of the correlator in the continuum limit are obtained and the bulk viscosity zeta is extracted via a Kubo formula.
Shear spectral sum rule in a nonconformal gravity dual
A sum rule which relates a stress-energy tensor correlator to thermodynamic functions is examined within the context of a simple nonconformal gravity dual. Such a sum rule was previously derived
