The study of exclusive processes in photon-induced interactions allows us to probe the generalized parton distributions (GPDs), which provide information about the 3-dimensional description of the quark and gluon content of hadrons. In this paper we

In this letter we complement previous studies on exclusive vector meson photoproduction in hadronic collisions presenting a comprehensive analysis of the t-spectrum measured in exclusive ρ and J/Ψ photoproduction in pA collisions at the LHC. We com

In this paper we investigate the possibility of searching for the hidden - bottom pentaquark states in photon – induced interactions at the LHC. We consider the presence of the Pb resonance in the s – channel of the γp→ϒp reaction and estimat

The exclusive production of axionlike particles (ALPs) by gluon – induced interactions is investigated in this exploratory study considering pp and PbPb collisions for the energies of the next run of the Large Hadron Collider (LHC). Assuming the Du

In this letter we propose the search of dark photons in the decay of pions produced by γγ interactions in ultraperipheral PbPb collisions. The cross section is estimated considering an accurate treatment for the absorptive corrections and for the n

In this paper we investigate the production of pentaquark states in the photon – proton interactions present in hadronic collisions at the RHIC and LHC. We consider two phenomenological models for the J/Ψ photoproduction that consider the presence
