Anti-de Sitter/Conformal-Field-Theory calculation of screening in a hot wind

One of the challenges in relating experimental measurements of the suppression in the number of J/psi mesons produced in heavy ion collisions to lattice QCD calculations is that whereas the lattice calculations treat J/psi mesons at rest, in a heavy ion collision a c(c) over bar pair can have a significant velocity with respect to the hot fluid produced in the collision. The putative J/psi finds itself in a hot wind. We present the first rigorous nonperturbative calculation of the consequences of a wind velocity v on the screening length L-s for a heavy quark-antiquark pair in hot N=4 supersymmetric QCD. We find L-s(v,T)=f(v)[1-v(2)](1/4)/pi T with f(v) only mildly dependent on v and the wind direction. This L-s(v,T)similar to L-s(0,T)/root gamma velocity scaling, if realized in QCD, provides a significant additional source of J/psi suppression at transverse momenta which are high but within experimental reach.
