对LHC观测到高多重性事件的评论

Comments on the observation of high multiplicity events at the LHC

Mark Strikman

摘要:

我们分析了CMS合作在LHC观察到的高多重性事件的结构。我们认为,观测到的大部分相关性是由于产生了一对p_t > 15 GeV/c的喷流。我们还认为,高多重性事件是由于三种效应的组合:高潜在的多重性碰撞在小的碰撞参量,向上波动的胶子密度碰撞质子,和生产的强子分裂的dijet。通过数据分析,阐明了高多重数事件和胶子场随x变化的探测涨落的动力学机制。

英文摘要:

We analyze the structure of the high multiplicity events observed by the CMS collaboration at the LHC. We argue that the bulk of the observed correlations is due to the production of a pair of jets with p_t > 15 GeV/c. We also suggest that high multiplicity events are due to a combination of three effects: high underlying multiplicity for collisions at small impact parameters, upward fluctuations of the gluon density in the colliding protons, and production of hadrons in the fragmentation of dijets. The data analysis is suggested which may clarify the underlying dynamics of the high multiplicity events and probe fluctuations of the gluon field as a function of x.
