2002年5月23日 · In this paper we study the pp-> ttH(H-> tau tau) channel at the LHC, for the case of a scalar Higgs boson, and use the obtained results to improve on existing strategies toward …
ttH, ttZ and ttW measurements at LHC and top quark compositeness
2017年3月15日 · Abstract: This note is an attempt to interpret some excesses, not yet significant due to systematics, observed by ATLAS and CMS in various analyses related to the standard …

the signal strength of tth production alone is not su -cient to unveil the nature of the Higgs-top coupling in Eq.1. Therefore, it is essential to investigate the kine-matical distributions of t th …
Impact of Minimal Composite Higgs on the ttH, ttHH, processes at LHC. Minimal Composite Higgs Models (MCHM) are a well motivated extension of the Standard Model (SM). At the scale ≈1 …
双光子通道中希格斯玻色子与顶夸克的耦合！ - 哔哩哔哩
2018年欧洲核子研究中心 (CERN)ATLAS和CMS合作项目宣布，观测到希格斯玻色子与一个名为“ttH”的顶夸克对产生。 这个结果是第一次观察到希格斯玻色子与夸克的耦合，紧随其后的是 …
(tH process) can happen at LHC in two ways: in association with a light quark (tHq) or in associ-ation with a W boson (tHW). In the Standard Model (SM) the production cross section for the …
• The tthh production cross-section is around 1 fb at tree level whereas tth is about 500 times larger. • Therefore the aim at HL-LHC will be to evidence this process and discover if a strong …
CMS实验发现ttH物理过程，高能所CMS组作出关键贡献
2018年6月5日 · ttH是这四种产生模式中唯一通过和费米子直接耦合的过程，其产生截面仅相当于ggH的1%左右，是LHC实验分析上最具挑战的物理过程之一。 此次CMS观测到5.2倍显著度 …
顶夸克对与矢量玻色子产生研究：对LHC搜寻ttH的影响
2024年7月15日 · 通过将NLO计算与parton淋浴匹配，作者分析了tt V 和tt VV 对LHC第二阶段tt H 分析（如双光子、双同号轻子及三到四个轻子的最终状态签名）的影响。 " 这篇论文是开放获 …
