摘要

我们计算了极低p tj / ψ的相干光产生的中心性依赖关系相对论重离子对撞机(RHIC)和大型强子对撞机(LHC)的能量在影响参数相关的饱和彩色偶极子模型中。利用大的等效光子通量，给出了由。产生的极低压强tj / ψ的微分截面外围重离子碰撞中的相干光子核。数值结果表明，我们的计算结果与相对论重离子对撞机(RHIC)能量下外围重离子碰撞的J / ψ数据一致。

Coherent Photoproduction of Low- p T Charmonium in Peripheral Heavy Ion Collisions

We calculate the centrality dependence for coherent photoproduction of very low-

p_{T}

J / ψ

at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies within the impact parameter-dependent saturated color dipole model. By using the large equivalent photon fluxes, we present the differential cross-section of very low-

p_{T}

J / ψ

produced by coherent photonuclear in peripheral heavy ion collisions. The numerical results demonstrate that our calculation agrees with

J / ψ

data in peripheral heavy ion collisions at Relativistic Heavy Ion Collider (RHIC) energies.
