Coherent and incoherent production of vector mesons in ultraperipheral collisions of xenon ions within the QCD parton saturation approach

Abstract: In this paper, we analyze the exclusive vector meson photoproduction in the recent run using xenon ions at energy of 5.44 TeV performed by the Large Hadron Collider. We focus on the ultraperipheral collisions and provide theoretical predictions for coherent and incoherent cross sections within the color dipole approach and gluon saturation framework. The rapidity distribution is investigated in both cases and comparison to other approaches available in the literature is completed. We show that the expected yie… Show more

“…The recent measurements [1][2][3][4][5][6] of exclusive production of J/ψ mesons in ultraperipheral heavy-ion collisions at the LHC have attracted much attention. At high energies, the diffractive photoproduction of the J/ψ meson can be described in the color dipole picture, see for example numerous approaches [7][8][9][10][11][12][13][14][15][16][17][18]. In the dipole approach the imaginary part of the diffractive production amplitude in forward direction takes the form ℑmA(γA → V A; W, q = 0) = 2…”

“…This however is not a complete review of the available literature, nor can we, due to space limitations, provide extensive discussions of the merits and shortcomings of different approaches. For applications of the color dipole approach to UPCs, some of them extending to light vector mesons and excited states, we refer the reader to [40][41][42][43][44][45][46][47][48][49][50][51][52]. The momentum space formulation, k ⊥factorization, which is equivalent to the dipole approach was used in [53], where also qqg-states were included.…”

“…[33][34][35][36][37], where the predictions for transverse momentum and rapidity distributions considering different phenomenological models were estimated. Machado et al studied the inclusive and exclusive J/ψ, ψ(2S), and Υ photoproductions in the proton-nucleus and nucleusnucleus collisions at LHC within the color dipole formalism [38][39][40][41]. In Refs.…”
