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 کاملElectroproduction of Kaons up to Q 2 =3 (gev/c)
This is a re-submission of the Conditionally Approved PR94-108. The experiment will measure exclusive kaon production cross sections in the H(e,eK)Y reaction. This experiment will measure how kaons are produced { the electromagnetic structure and which to what extent the various production mechanisms contribute. Three of the four unpolarized response functions will be separated over a large ran...
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 کاملTransversity GPD in photo- and electroproduction of two vector mesons
The chiral-odd generalized parton distribution (GPD), or transversity GPD, of the nucleon can be accessed experimentally through the photoor electroproduction of two vector mesons on a polarized nucleon target, γN → ρ1ρ2N , where ρ1 is produced at large transverse momentum, ρ2 is transversely polarized, and the mesons are separated by a large rapidity gap. We predict the cross section for this ...
