Two topics on charge exchange (ChEx) production of exclusive systems of light mesons by pions on nuclei will be presented. The first one is the completed study of the omega(782) phi(1020) channel with the dominance of the scalar isoscalar resonance f0(1710), which characteristics point to its glueball-like nature. The second one is a preliminary report on the first observation of... -

Recent results of proton-Pb collisions with large forward rapidity gap events at the LHC show a dominant role of photon exchange over pomeron one.
A comparison of LHC proton-proton, proton-nuclear forward rapidity gap events provides an opportunity for the estimation of
A- and Z- dependencies of pomeron- and photon- exchange contributions, respectively. -

László Jenkovszky, Érison S. Rocha, Magno V. T. Machado - Light vector meson photoproduction in ultraperipheral heavy-ion collisions at the LHC within the Reggeometric Pomeron approach - https://doi.org/10.1002/asna.20220117
Abstract By using the Reggeometric Pomeron model for vector meson production which successfully describes the high energy lepton-nucleon data, we analyze the... -

Various hadron ”radii” that appear in the literature, e.g.”charge”, ”gravitational”, etc, do not have a direct geometric meaning and do not give an idea of the physical size of a hadron. They, however, can be used to estimate the genuine sizes of hadrons. In the framework of the Gribov-Feynman parton scheme we show that at high enough energy a gluon cloud appears beyond the valence... -
