摘要:

紧凑型线性对撞机(CLIC)是未来e+e对撞机的一个选项,其质心能量高达3 TeV,可对各种新物理现象提供灵敏度,并在能源前沿进行精确的物理测量。本文是第一次全面介绍的希格斯物理达到CLIC运行在三个能量阶段:sqrt(s)= 350 GeV,1.4 TeV和3 TeV。操作的初始阶段允许在Higgsstrahlung(e+e- -> ZH)和WW-fusion(e+e- -> Hnunu)中研究希格斯玻色子的产生,从而精确测量产生截面、Higgs总衰变宽度Gamma_H和独立于模型的Higgs耦合的确定。在sqrt(s)> 1 TeV的操作提供了通过WW-fusion产生的希格斯玻色子的高统计样本,使得能够对希格斯玻色子耦合进行严格约束。对更罕见的过程e+e- -> ttH和e+e- -> HHnunu的研究允许测量顶部汤川耦合和希格斯玻色子自耦合。本文介绍了详细的研究,在CLIC的希格斯粒子测量可实现的精度,并描述了这些测量的解释在一个全球性的适合。

英文摘要:

The Compact Linear Collider (CLIC) is an option for a future e+e- collider operating at centre-of-mass energies up to 3 TeV, providing sensitivity to a wide range of new physics phenomena and precision physics measurements at the energy frontier. This paper is the first comprehensive presentation of the Higgs physics reach of CLIC operating at three energy stages: sqrt(s) = 350 GeV, 1.4 TeV and 3 TeV. The initial stage of operation allows the study of Higgs boson production in Higgsstrahlung (e+e- -> ZH) and WW-fusion (e+e- -> Hnunu), resulting in precise measurements of the production cross sections, the Higgs total decay width Gamma_H, and model-independent determinations of the Higgs couplings. Operation at sqrt(s) > 1 TeV provides high-statistics samples of Higgs bosons produced through WW-fusion, enabling tight constraints on the Higgs boson couplings. Studies of the rarer processes e+e- -> ttH and e+e- -> HHnunu allow measurements of the top Yukawa coupling and the Higgs boson self-coupling. This paper presents detailed studies of the precision achievable with Higgs measurements at CLIC and describes the interpretation of these measurements in a global fit.
