The exclusive photoproduction of meson states from protons, (with ), is studied in ultraperipheral Pb collisions at a centre-of-mass energy per nucleon pair of . The measurement is performed using the decay mode, with data collected by the CMS experiment corresponding to an integrated luminosity of 32.6 . Differential cross sections as functions of the transverse momentum squared , and rapidity y , are presented. The photoproduction cross section is extracted in the rapidity range , which corresponds to photon–proton centre-of-mass energies in the range . The data are compared to theoretical predictions based on perturbative quantum chromodynamics and to previous measurements.

“…There would be an additional uncertainty related to the vector meson wave function (for details on the size of the related uncertainty, see, e.g., Ref. [6]). At central rapidity, one predicts explicitly dσ coh =dyðy ¼ 0Þ ¼ 148.3 AE 10.3 mb and dσ coh = dyðy ¼ 0Þ ¼ 30.5 AE 1.8 mb for ρ and ϕ, respectively.…”

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 yields are enough to perform reliable cross section measurements for light mesons as ρ 0 and ϕ.

“…In addition the resonant φ(1020) and non-resonant (Drell-Söding) K + K − photoproduction mechanisms will be discussed. So far the cross sections for the exclusive pp → ppφ(1020) reaction were calculated within a pQCD k t -factorization approach [41], and in a color dipole approach [42,43].…”

We present a study of the central exclusive production of the K + K − pairs in proton-proton collisions at high energies. We consider diffractive mechanisms including the K + K − continuum, the dominant scalar f 0 (980), f 0 (1500), f 0 (1710) and tensor f 2 (1270), f ′ 2 (1525) resonances decaying into the K + K − pairs. We include also photoproduction mechanisms for the non-resonant (Drell-Söding) and the φ(1020) resonance contributions. The theoretical results are calculated within the tensor-pomeron approach including both pomeron and reggeon exchanges. Predictions for planned or current experiments at RHIC and LHC are presented. We discuss the influence of the experimental cuts on the integrated cross section and on various differential distributions for outgoing particles. The distributions in two-kaon invariant mass, in a special "glueball filter variable", as well as examples of angular distributions in the K + K − rest frame are presented. We compare the φ(1020) and continuum photoproduction contributions to the f 0 (980) and continuum diffractive contributions and discuss whether the φ(1020) resonance could be extracted experimentally. For the determination of some model parameters we also include a discussion of K-nucleon scattering, in particular total cross sections, and of φ(1020) photoproduction.
