AbstractAbstract
[en] The effects of hard-gluon bremsstrahlung in dimuon and UPSILON production are studied. It is shown that in pp interactions the transverse-momentum distribution is broader for UPSILON production than for dimuon production. Furthermore, this difference increases markedly with energy. On the contrary, this effect should not be present for p-barp interactions. Predictions for π+- and K+- beams are also discussed
