One of the challenges in relating experimental measurements of the suppression in the
number of J/ψ mesons produced in heavy ion collisions to lattice QCD calculations is that
whereas the lattice calculations treat J/ψ mesons at rest, in a heavy ion collision acc¯ pair
can have a significant velocity with respect to the hot fluid produced in the collision. The
putative J/ψ 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 …

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 cc 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
