论文摘要
我们通过在相对论重离子碰撞器（RHIC）和大型HADRON Collider（LHC）Energies中，通过半相结合和连贯的两光子相互作用来计算$χ_{C} $和$η_{C} $的产生。 $ ab \ stackrel {γγ} {\ longrightArrow} ahb $的横向动量分布和快速分布的差分横截面（h = $χ_{C} $和$η_{C} $）是通过使用在Ultra-peripheral nucleus-nucleus-nucleus coldisions中的等效光子近似来估计的。数值结果表明，在rhic和lhc能量上，在超核核核碰撞中的$χ_{C} $和$η_{C} $的实验研究是可行的。
We calculate the production of $χ_{c}$ and $η_{c}$ by the semi-coherent and coherent two-photon interaction in ultra-peripheral heavy ion collisions at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies. The differential cross section of transverse momentum distribution and rapidity distribution for $AB\stackrel{γγ}{\longrightarrow}AHB$ (H=$χ_{c}$ and $η_{c}$), are estimated by using the equivalent photon approximation in ultra-peripheral nucleus-nucleus collisions. The numerical results demonstrate that the experimental study of $χ_{c}$ and $η_{c}$ in ultra-peripheral nucleus-nucleus collisions is feasible at RHIC and LHC energies.
