It is argued that the ratio Γ((Q¯Q)′→(Q¯Q)η)Γ((Q¯Q)′→(Q¯Q)ππ) of hadronic transition rates between heavy quarkonium states is calculable within quantum chromodynamics in terms of triangle a

The total cross section fore+e− annihilation into hadrons for center of mass energies from 9.4 to 9.5 GeV has been measured with the nonmagnetic DESY-Heidelberg detector at DORIS. A value ofR=σhad/σµµ=3.8±0.

The triplicity method was used to search for triple jets in the decay of T(9.46) into charged and neutral hadrons as an indication of the 3-gluon decay of the T. A comparison of the results with phase space, qij and 3-gluon predict

We have calculated charm pair production in ν μ N collisions using quantum chromodynamics (QCD). The resulting trimuon rate turns out to be small at present energies: σ(3μ) σ(1μ)≲10 −6 at E ν =

Transverse-momentum spectra are calculated for heavy quarkonium states QQ¯ (Jψ,ϒ) produced in pp and p¯p collisions. These transverse momenta result from the hard quark (q) and gluon (g) subprocesses qq¯
