Abstract Information about the three-dimensional description of the quark and gluon content of hadrons, described by the generalized parton distributions (GPDs), can be probed by exclusive processes in electron–proton (ep) collisions. In this lette

Abstract We investigate the exclusive $$J/\psi $$ J / ψ production at the future Electron-ion collider in China by utilizing the eSTARlight event generator. We model the cross-section and kinematics by fitting to the world data of $$J/\psi $$ J / ψ

Abstract The exclusive dilepton photoproduction in pp and pAu collisions at RHIC is investigated considering the contribution of the Bethe–Heitler (BH) and the timelike Compton scattering (TCS) processes. The TCS amplitude is estimated at next-to-l

Abstract In this work, the $$\gamma p\rightarrow \phi (1680) p$$ γ p → ϕ ( 1680 ) p reaction is systematically studied based on the two gluon exchange model and the pomeron model. The calculation results show that the total cross section of $$\ph

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

Abstract Exclusive production of charmonium-like XYZ states in hadron–hadron ultraperipheral collisions (UPCs) and electron–proton scattering are studied employing the effective Lagrangian method. Total cross sections and rapidity distributions o

Abstract The near-threshold photoproduction of $$J/\psi $$ J / ψ is regarded as one golden process to unveil the nucleon mass structure, pentaquark state involving the charm quarks, and the poorly constrained gluon distribution of the nucleon at lar

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
