在ILC上Higgs与ZHH的自耦合分析

Analysis of Higgs Self-coupling with ZHH at ILC

Yosuke Takubo

摘要:

对ee->ZHH截面的测量提供了三线性Higgs自耦合的信息,这对确定电弱对称性破缺的机制具有重要意义。由于信号区存在巨大的背景,背景剔除是识别ZHH事件的关键。本文研究了利用ZHH->vvHH/qqHH事例在ILC观测$ZHH$事例的可能性。

英文摘要:

Measurement of the cross-section of ee->ZHH offers the information of the trilinear Higgs self-coupling, which is important to confirm the mechanism of the electro-weak symmetry breaking. Since there is huge background in the signal region, background rejection is key point to identify ZHH events. In this paper, we study the possibility to observe the $ZHH$ events at ILC by using ZHH->vvHH/qqHH events.
