0 ) - Renormalization Group for Many Particle Exclusive and Exclusive Semi - Inclusive Processes
In this paper it is shown that in QCD a new set of high energy processes are calculable. Firstly, many meson exclusive processes are shown to be control-lable. Secondly, a new type of exclusive semi-inclusive + meson process (for example e + e-+ ncone + anything, where II is unaccompanied in phase space) is shown to be controllable by renormalization group approach. Possible experimental confro...
متن کاملTransversity in Exclusive and Inclusive Processes
Both meson photoproduction and semi-inclusive deep inelastic scattering can potentially probe transversity properties of the nucleon. We explore how that potential can be realized dynamically. The role of rescattering in both exclusive and inclusive meson production as a source for single spin asymmetries is examined. Using a dynamical model, we evaluate the spin independent cos2φ asymmetry ass...
متن کاملOptimal Renormalization Scale and Scheme for Exclusive Processes
We use the BLM method to x the renormalization scale of the QCD coupling in exclusive hadronic amplitudes such as the pion form factor and the photon-to-pion transition form factor at large momentum transfer. Renormalization-scheme-independent commensurate scale relations are established which connect the hard scattering sub-process amplitudes that control exclusive processes to other QCD obser...
متن کاملExclusive channels in semi - inclusive production of pions and kaons
We investigate the role of exclusive channels in semi-inclusive electroproduction of pions and kaons. Using the QCD factorization theorem for hard exclusive processes we evaluate the cross sections for exclusive pseudoscalar and vector meson production in terms of generalized parton distributions and meson distribution amplitudes. We investigate the uncertainties arising from the modeling of th...
متن کاملExclusive and Semi-inclusive B Decays in QCD Factorization
Applications of QCD factorization to B → φK, charmless B → V V , B → J/ψK(K∗) and semi-inclusive decays B →MX are discussed.
