QCD corrections to the reactionp + \bar p \to W + \gamma + X

The complete order α _S QCD corrections to the cross section and differential distributions for \(p + \bar p \to W + \gamma + X\) are presented. At the quark level this involves the computation of the contributions from the reactions \(q + \bar q \to W + \gamma + g and q(\bar q) + g \to W + \gamma + q + (\bar q)\) . We discuss how these corrections modify the factorization property of the lowest order amplitude and give results for future experiments at CERN and Fermilab.     

QCD radiative corrections to the decayW \to q\bar q\gamma

The complete order α _s QCD corrections to the rate and the Dalitz plot for \(W \to q\bar q\gamma \) are presented. We discuss how these corrections modify the factorization property of the lowest order decay rate.     

A study of the reaction p + p → p + p + X at ISR energies

We have performed an experiment to investigate the reaction p + p → p₁ + p₂ + X at the CERN Intersecting Storage Rings (ISR). The dependence of the cross-section on the mass and rapidity of the system X, and on the momentum transfer squared t₁, t₂ to the outgoing protons is studied. We observe signals for the production of ?, ω, f, and A₂ mesons in the missing-mass spectra, and conclusions are made about the contribution of double-Pomeron exchange.
