WebThe photoproduction of quarkonium in coherent hadron-hadron (pp/pA/AA) interactions for LHC energies is an important tool to investigate the QCD dynamics at high energies. In this paper we estimate the integrated cross section and rapidity distribution for J/Ψ and Υ production using the Color Glass Condensate (CGC) formalism. We predict large rates, … WebNear-threshold Photoproduction of ϕ italic-ϕ \phi italic_ϕ Mesons from Deuterium X.

A fresh look at diffractive 𝐽/𝜓 photoproduction at HERA, with ...
WebAn analysis of light vector meson photoproduction at small Bjorken x ≤ 0.2 is done on the basis of the generalized parton distributions (GPDs). Our results on the cross section and spin density matrix elements (SDME) are in good agreement with experiments. This report is devoted to the study of the vector meson leptoproduction at Bjorken WebFeb 26, 2024 · We propose a model based on Regge theory to describe photoproduction of light vector mesons. We fit the SLAC data and make predictions for the energy and momentum transfer dependence of the spin-density matrix elements in photoproduction of , and mesons at GeV, which are soon to be measured at Jefferson Lab.

Exclusive vector meson production at an electron-ion collider
WebThe vector mesons consisting of light quarks form a nonet. In high energy physics , a vector meson is a meson with total spin 1 and odd parity (usually noted as J P = 1 − ). Vector … WebFeb 6, 2024 · For light vector meson photoproduction, because the exchange of a scalar quark-antiquark pair is not suppressed and should dominate the scalar gluon exchange, the radius we extract from ρ0 photoproduction is likely to … Webinelastic lepton-nucleus scattering at small values of the Bjorken variable x = Q2/2Mv. 1.
