$\sqrt{s}=$ 13 TeV质子-质子碰撞最小偏压事件中带电粒子谱的测量

Measurement of charged particle spectra in minimum-bias events from proton-proton collisions at $\sqrt{s}=$ 13 TeV

CMS Collaboration

摘要:

赝快度,横向动量和多重性分布测量的赝快度范围$|η| <$ 2.4的带电粒子的横向动量满足$p_\mathrm{T} >$ 0.5 GeV的质子-质子碰撞在一个$\sqrt{s} =$ 13 TeV的质心能量。测量结果分为三个不同的事件类别。最具包容性的类别对应于非弹性PP数据集,而其他两个类别是非弹性样品的排他性子集,其在单个衍射解离事件中被增强或耗尽。的测量结果进行了比较,用于描述高能强子对撞机和宇宙射线物理相互作用的蒙特卡罗事件发生器的预测。

英文摘要:

Pseudorapidity, transverse momentum, and multiplicity distributions are measured in the pseudorapidity range $|η| <$ 2.4 for charged particles with transverse momenta satisfying $p_\mathrm{T} >$ 0.5 GeV in proton-proton collisions at a center-of-mass energy of $\sqrt{s} =$ 13 TeV. Measurements are presented in three different event categories. The most inclusive of the categories corresponds to an inelastic pp data set, while the other two categories are exclusive subsets of the inelastic sample that are either enhanced or depleted in single diffractive dissociation events. The measurements are compared to predictions from Monte Carlo event generators used to describe high-energy hadronic interactions in collider and cosmic-ray physics.
