论文摘要
我们分析了不同RHIC和LHC能量和中心的PP,PPB,XEXE和PBPB碰撞的横向动量分布,以及HIGGS生产衰减成$γγ$和4L的相应分布。在有效的热温度和硬尺度之间发现了简单的线性关系,对所有过程近似有效,主要由硬尺度波动确定。为了进一步,可以通过单个函数来描述整个PP碰撞的整个频谱,表明热温仅取决于硬尺度及其波动。探索了软尺度和硬尺度的多样性之间的可能关系。
We analyze the transverse momentum distributions of pp, pPb, XeXe and PbPb collisions at different RHIC and LHC energies and centralities as well as the corresponding distributions for Higgs production decaying into $γγ$ and 4l. A simple linear relation is found between the effective thermal temperature and the hard scale, approximately valid for all processes and mainly determined by the hard scale fluctuations. In order to go further, it is shown that the whole spectrum of pp collisions can be described by a single function showing that the thermal temperature is determined solely by the hard scale and its fluctuations. The possible relation between the multiplicities of the soft and hard scales is explored.
