论文摘要
质子和核的超疗法碰撞（UPC）对于研究载体介子和外来状态的光生物生产至关重要。通过使用Starlight Package研究了Pentaquark共振频道中矢量介子在$ p \ mbox { - } au $ upcs和$ p $ - $ pb $ upcs的$ p \ mbox { - } au $ upcs。使用有效的拉格朗日方法获得了通过五夸克状态共振通道的向量介子的横截面。 $ j/ψ$和$υ（1s）$的伪宽度和速度分布均以RHIC的$ P \ Mbox { - } au $ UPC和LHC的$ p $ - $ PB $给出。发现RHIC比LHC是发现五夸克州的更好平台。此外，$ p_ {b}（11080）$比$ P_C（4312）$更易于识别，因为RHIC的$υ（1S）$的背景比$ t $ channel中的$差（1S）$弱。
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 $J/ψ$ and $Υ(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 $Υ(1S)$ is weaker than $J/ψ$ in the $t$-channel at the RHIC.
