Query: Transverse Momentum of Psi and Dimuon Production in Pb+Pb Collisions   CERN collaboration NA50 has measured charmonium and Drell-Yan dimuon
production in Pb+Pb collisions. Parton scattering broadens the transverse
momentum, p_T, distributions for these processes. We predict that the average
p_T^{2} will flatten in Pb+Pb collisions as a function of the neutral
transverse energy of hadrons, E_T, in contrast to the almost-linear rise seen
in S+U - psi +X. If seen, such a flattening will support hadronic explanations
of charmonium suppression. Figures 2 and 5 are improved and numerous
typographical errors are corrected.
