新物理模型中的Higgs粒子在高能对撞机上的唯象学研究

To solve the problems of triviality and unnaturalness with the introduction of Higgs field of the Standard Model, people have put forward many new physics models. Some of these models are remained popular candidates for new physics, such as the littlest Higgs model with T-parity, the simplest little Higgs model and the left-right twin Higgs model. Now, probing the Higgs boson and new physics are the important research tasks at the Large Hadron Collider (LHC), the International Linear Collider (ILC) and the other Higgs factories. This project focuses on the study of Higgs boson at the high energy colliders and the new physics models mentioned above. The content includes three aspects as follows: (1) Study of the new physics effects related to neutral Higgs boson production processes at the LHC; (2) Study of the new physics effects related to neutral Higgs boson production processes at the ILC and other Higgs factories; (3) Study of the new physics effects related to charged Higgs boson production processes at the LHC and ILC. 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 these new physics models.

为了解决标准模型中Higgs场的引入带来的平庸性、不自然性等问题，人们提出了许多新物理模型。其中，具有T-宇称的最小Higgs模型、最简单的小Higgs模型、左右双Higgs模型均为流行的新物理候选者。大型强子对撞机(LHC)、国际直线对撞机（ILC）以及其它Higgs工厂均把探测Higgs粒子和新物理作为重要的研究目标。本项目主要围绕以上几种高能对撞机和新物理模型对Higgs粒子进行三方面的研究：（1）研究LHC上与中性Higgs粒子产生有关的新物理效应；（2）研究ILC和其它Higgs工厂上与中性Higgs粒子产生有关的新物理效应；(3) 研究LHC和ILC上与带电Higgs粒子产生有关的新物理效应。这些研究不仅可为探测Higgs粒子的精确实验提供指导，而且也可为检验这几种新物理模型提供重要的线索和依据。
