摘要: Abstract Intrinsic (primordial) transverse momenta of quarks and gluons are calculated as well those arising from recoil (bremsstrahlung) effects, using only the well-known parton distributions input. The intrinsic kT's lie typically in range 150–250 MeV. Recent approaches heuristic integro-differential equations for kT partons shown to disagree with results obtained by rigorous QCD calculations. dimuon pairs produced pp → μ+μ− + X at ISR can be solely explained dynamical i.e., q →(μ μ − ) g gq , no significant required. These show a pronounced energy dependence which could easily tested CERN ISR. disagreement occurs average 〈pT2〉, but not 〈pT〉, observed pN collisions. Possibilities resolve this problem discussed. Our also compared previous theoretical analyses.
