Production of vector mesons in pentaquark states resonance channel in $p$-$A$ ultraperipheral collisions

Abstract

Ultraperipheral collisions (UPCs) of protons and nuclei are important for the study of the photoproduction of vector mesons and exotic states. The photoproduction of vector mesons in the pentaquark resonance channel in $p\mbox{-}Au$ UPCs at the Relative Heavy Ion Collider (RHIC) and $p$-$Pb$ UPCs at the Large Hadron Collider (LHC) is investigated by employing STARlight package. The cross sections of vector mesons via pentaquark state resonances channel are obtained using effective Lagrangian method. The pseudo-rapidity and rapidity distributions of $J/\psi$ and ${\rm Y}(1S)$ are given for $p\mbox{-}Au$ UPCs at the RHIC and $p$-$Pb$ at the LHC. It is found that the RHIC is a better platform for discovering the pentaquark states than the LHC. Moreover, $P_b(11080)$ is easier to identify than $P_c(4312)$ because the background of ${\rm Y}(1S)$ is weaker than $J/\psi$ in the $t$-channel at the RHIC.
