Heavy Vector Meson Production at Hera
Representing the H1 and ZEUS collaborations Recent results from the HERA experiments H1 and ZEUS on the exclusive production of heavy vector mesons V in ep collisions, i.e. the reaction ep ! eV p, are reviewed. The new measurements 1 include photoproduction of J== at larger photon-proton centre-of-mass energy W than previously, more precise data on J== electroproduction and (2S) photoproduction...
متن کاملTheory of Vector Meson Production
I discuss the theoretical status of the 'soft' pomeron and its place in describing generic diffractive processes. The role of perturbative QCD (pQCD) corrections is considered, in particular in the context of quasi-elastic vector meson production at high Q 2. In those processes where short distances are dominant, the 'hard' (pQCD) pomeron is expected to reveal itself, such a process may well be...
متن کاملHeavy Vector Meson Measurement in the PHENIX Experiment
The primary goal of the PHENIX collaboration is the detection and characterization of the quark-gluon plasma. One of the proposed signatures of the quark-gluon plasma is the suppression of J/ production 1. We will outline the capabilities of the PHENIX experiment for measuring leptonic decays of the J/ and other quarkonium states.
متن کاملDiffractive heavy vector meson production from the BFKL equation
Diffractive heavy vector meson photoproduction accompanied by proton dissociation is studied for arbitrary momentum transfer. The process is described by the non-forward BFKL equation, for which a complete analytical solution is found, giving the scattering amplitude. The impact of non-leading corrections to the BFKL equation is also analysed. Results are compared to the HERA data on J/ψ produc...
