Inelastic Photo-and Electroproduction of Charmonium
Measurements of inelastic production of charmonium with the ZEUS detector at HERA are presented. J/ψ and ψ′ mesons have been identified using the decay channel ψ → μμ. The data, corresponding to an integrated luminosity of 38 pb in photoproduction and 73.3 pb in electroproduction, are confronted to theoretical predictions.
متن کامل1 Hyperon photo - and electroproduction at CLAS
(Received: February 7, 2008) The large acceptance and high multiplicity capabilities of the CLAS detector make it possible to study a wide range of previously unmeasured strange baryon production processes. Studies of the decay angular distributions of electroproduced strange baryons have yielded several interesting new results. The Λ(1520) electroproduction decay angular distributions shed lig...
متن کاملHeavy-flavor Photo-and Electroproduction at Nlo
We review one-particle inclusive production of heavy-flavored hadrons in a framework which resums the large collinear logarithms through the evolution of the FFs and PDFs and, at the same time, retains the full dependence on the heavy-quark mass without additional theoretical assumptions. The main focus is on the production of D ⋆ mesons in deep inelastic electron–proton scattering at HERA. We ...
متن کاملExclusive Photo-and Electroproduction of Mesons in the Gev Region
We consider the reactions γ p → M B, with M B being either K + Λ, K + Σ 0 , or π + n, within a diquark model which is based on perturbative QCD. The model parameters and the quark-diquark distribution amplitudes of the baryons are taken from previous investigations of electromagnetic baryon form factors and Compton-scattering off protons. Reasonable agreement with the few existing photoproduc-t...
متن کاملPion photo- and electroproduction and the partially conserved axial current
The relevance of the axial current for pion production processes off the nucleon with real or virtual photons is revisited. Employing the hypothesis of a partially conserved axial current (PCAC), it is shown that, when all of the relevant contributions are taken into account, PCAC does not provide any additional constraint for threshold production processes that goes beyond the Goldberger-Treim...
