摘 要:本文在具有T宇称的最小希格斯(LHT)模型下,对大型强子对撞机上单希格斯粒子和顶夸克对联合产生过程 进行了研究。结果发现,在合理的参数空间范围内,LHT模型与标准模型中该过程散射截面值之比小于1,仍然低于目前实验结果。这些研究不仅可为探测希格斯粒子与顶夸克的耦合提供指导,而且也可为检验LHT模型提供重要的线索和依据。31690 毕业论文关键词:顶夸克;希格斯粒子;LHT模型;大型强子对撞机
The Study of the Process in the Littlest Higgs Model with T-parity at the LHC
Abstract: In this work, we investigate the Higgs-boson and the top quark paris production processes in the littlest Higgs model with T-parity at the Large Hadron Collider(LHC). We calculated the production cross sections. In the allowed parameter space, compare with the standard model predictions, we find that the value of the cross sections always less than 1. It is still lower than the results of experimental. These studies not only can provide some theoretical guidance for detecting the Higgs bosons in experiment, but also can provide some clue and evidence to test new physics models.
