Interference in exclusive vector meson production in heavy-Ion collisions
Vector mesons are produced copiously in peripheral relativistic heavy-ion collisions. Virtual photons from one ion can fluctuate into quark-antiquark pairs and scatter from the second ion, emerging as vector mesons. The emitter and target are indistinguishable, so emission from the two ions will interfere. Vector mesons have negative parity so the interference is destructive, reducing the produ...
متن کاملExclusive Vector Meson Production in Relativistic Heavy Ion Collisions
Exclusive vector meson production reactions such as Au + Au → Au + Au + V, where V = ρ, ω, φ or J/ψ can proceed through photon-Pomeron and photon-meson interactions. Photons from the electromagnetic field of one nucleus interact coherently with the other nucleus. Photonuclear cross sections are scaled from γp data, and convoluted with the photon spectrum to find the exclusive rates. The cross s...
متن کاملVector Meson Production at a Polarized HERA Collider
A successful interpretation of the cross sections for elastic and inelastic vector meson production can be made if one assumes the underlying dynamics to be governed by hard partonic subprocesses. Extending these partonic approaches to longitudinally polarized electron-proton collisions, we estimate the expected production asymmetries at the HERA collider. The anticipated statistical errors on ...
متن کاملExclusive vector meson production at HERA from QCD with saturation
Following recent predictions that the geometric scaling properties of deep inelastic scattering data in inclusive γp collisions are expected also in exclusive diffractive processes, we investigate the diffractive production of vector mesons. Using analytic results in the framework of the BK equation at non-zero momentum transfer, we extend the QCD-inspired saturation model to parametrise the mo...
متن کاملExclusive Meson Production at NLO
Generalized parton distributions (GPDs) are a versatile tool to quantify important aspects of hadron structure in QCD. They contain unique information on the spatial distribution of partons [1] and on the orbital angular momentum they carry in the proton [2]. The theoretically cleanest process where GPDs can be studied is deeply virtual Compton scattering (similar to inclusive DIS, which plays ...
