$\sqrt{s}$ = 13 TeV pp碰撞中$τ$轻子对衰变模中包含和微分希格斯玻色子产生截面的测量

Measurement of the inclusive and differential Higgs boson production cross sections in the decay mode to a pair of $τ$ leptons in pp collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration

摘要:

本文用$τ$轻子衰变道测量了希格斯玻色子的包容和微分基准截面。微分截面的测量作为函数的希格斯玻色子玻色子的横向动量,射流的多重性,和横向动量的领先射流的事件中,如果有的话。分析是使用收集的质子-质子数据与CMS检测器在大型强子对撞机在一个中心的质量能量为13 TeV,对应于138 fb $^{-1}$的积分亮度。这是两个$τ$轻子末态下希格斯玻色子截面的首次微分测量。在具有大喷流多重性或洛伦兹增强的希格斯玻色子的最终状态下,这些测量比在其他最终状态下进行的测量有了显著的改进。

英文摘要:

Measurements of the inclusive and differential fiducial cross sections of the Higgs boson are presented, using the $τ$ lepton decay channel. The differential cross sections are measured as functions of the Higgs boson transverse momentum, jet multiplicity, and transverse momentum of the leading jet in the event if any. The analysis is performed using proton-proton data collected with the CMS detector at the LHC at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 138 fb$^{-1}$. These are the first differential measurements of the Higgs boson cross section in the final state of two $τ$ leptons. In final states with a large jet multiplicity or with a Lorentz-boosted Higgs boson, these measurements constitute a significant improvement over measurements performed in other final states.
