摘要:

在大型强子对撞机的最大的碰撞能量在pp碰撞的可用性允许一个显着的进步,在测量$J/ψ$生产作为事件多重性的函数。在LHC的$\sqrt{s} = 7\,\mathrm{TeV}$和RHIC的$\sqrt{s} = 0.2\,\mathrm{TeV}$观测到的有趣的相对增加的数据,现在正在$\sqrt{s} = 13\,\mathrm{TeV}$的前所未有的多重性进行研究。在中快度的双电子通道与ALICE的测量和讨论比较,从现有的理论模型和数据在较低的能量预测。

英文摘要:

The availability at the LHC of the largest collision energy in pp collisions allows a significant advance in the measurement of $J/ψ$ production as function of event multiplicity. The interesting relative increase observed with data at the LHC at $\sqrt{s} = 7\,\mathrm{TeV}$ and at RHIC at $\sqrt{s} = 0.2\,\mathrm{TeV}$ is studied now at unprecedented multiplicities at $\sqrt{s} = 13\,\mathrm{TeV}$. The measurement at mid-rapidity in the dielectron channel with ALICE is presented and discussed in comparison to predictions from available theoretical models and to data at lower energies.
