Transverse momenta of hadronically produced heavy-quark systems: 2 to 3 processes in quantum chromodynamics

Transverse-momentum spectra are calculated for heavy quarkonium states QQ (J/ psi , Upsilon ) produced in pp and pp collisions. These transverse momenta result from the hard quark (q) and gluon (g) subprocesses qq to QQg, gq to QQq, and gg to QQg. The p/sub T/ distributions for J/ psi production are...

description Transverse-momentum spectra are calculated for heavy quarkonium states QQ (J/ psi , Upsilon ) produced in pp and pp collisions. These transverse momenta result from the hard quark (q) and gluon (g) subprocesses qq to QQg, gq to QQq, and gg to QQg. The p/sub T/ distributions for J/ psi production are expected to be significantly steeper than for the mu /sup +/ mu /sup -/ continuum, whereas the two distributions become similar in the Upsilon mass region. These effects are partly confirmed by recent CERN ISR measurements. Predictions for pp collisions at square root s=540 GeV are also given. (26 refs).
