# On the infrared behavior of the shear spectral function in hot Yang-Mills theory

@article{Vuorinen2015OnTI, title={On the infrared behavior of the shear spectral function in hot Yang-Mills theory}, author={Aleksi Vuorinen and Yan Zhu}, journal={Journal of High Energy Physics}, year={2015}, volume={2015}, pages={1-27} }

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…
