论文摘要
我们通过LHC Energy地区的超长重离子碰撞在$ j/ψj/ψ$衰减通道中研究$ x(6900)$的生产。 $ x(6900)$的潜在量子号为$ 0^{\ pm +} $和$ 2^{\ pm +} $。我们发现$ x(6900)$的横向动量和极角分布可用于区分这四个潜在的量子数。这些典型的分布源于来自快速移动核的线性极化光子,并且可以通过LHC实验进一步测量。
We study the production of the $X(6900)$ through the $J/ψJ/ψ$ decay channel in the ultra-peripheral heavy ion collisions at the LHC energy region. The potential quantum numbers of $X(6900)$ would be $0^{\pm +}$ and $2^{\pm+}$. We find that the transverse momentum and the polar angle distributions of $X(6900)$ can be used to distinguish these four potential quantum numbers. These typical distributions stem from the linearly polarized photon from the fast-moving nuclei and can be measured with the LHC experiments in further.
