Shear and Bulk Viscosities of a Weakly Coupled Quark Gluon Plasma with Finite Chemical Potential and Temperature---Leading-Log Results

Jiunn-Wei Chen, Yen-Fu Liu, Yu-Kun Song +1

We calculate the shear (eta) and bulk (zeta) viscosities of a weakly coupled quark gluon plasma at the leading-log order with finite temperature T and quark chemical potential mu.…

Sudakov Resummation in Small-x Saturation Formalism

A. H. Mueller, Bo-Wen Xiao, Feng Yuan

Through an explicit calculation of massive scalar particle (e.g., Higgs boson) production in high energy pA collisions up to one-loop order, we demonstrate that the Sudakov-type lo…
