LHC发现Higgs类型的粒子后，进一步深入研究Higgs类型的粒子的性质，确认其是否标准模型的Higgs粒子或是其它新物理模型的Higgs粒子，成为了当前粒子物理的热点问题。而对Higgs粒子在LHC上产生和衰变的精确理论预言是研究上述问题的基础，甚至是关键。这样，由于在强子对撞机上高阶QCD效应是预言任何事例的信号和控制其标准模型本底的关键，故我们将进一步详细考察Higgs粒子各种有关过程的高阶QCD效应，包括固定阶效应和软胶子重求和效应。此外，我们还将深入研究如何计算一般带色末态的QCD次次领头阶水平的观测量，特别是红外减除方法；并将进一步研究顶夸克和规范玻色子等有关观测量的高阶QCD效应；同时深入探索包括超对称，额外维和暗物质等在内的新物理模型在LHC上可能的信号，并给出其在5σ水平上被发现的可能性；还将重点研究三规范玻色子耦合的性质以及Higgs场和宇宙学可能的关联。

At the Large Hadron Collider (LHC) both the ATLAS and CMS collaborations have found a Standard Model (SM) Higgs boson like particle. It is promising that LHC can tell whether this particle is the SM Higgs boson or something else when the measurement precision increases and its properties are probed. Hence, it is important to investigate higher order QCD effects ( including fixed-order and resummation calculations ) on Higgs physics in order to improve the theoretical predictions and reduce the uncertainties. Moreover, we will investigate the method of calculating the next-to-next-to-leading-order(NNLO) corrections in the processes with color final states, especially how to deal with infred divergences in the NNLO calculation. Besides, we will study the high order QCD effects on the top quark physics, gauge boson interaction, supersymmetry particles, gravitons and dark matter productions in various popular models and perform the Monte Carlo simulation at lest at NLO QCD level (showing the discovery significance at 5σ level). We will also study the properties of triple gauge boson couplings and the relation of Higgs field and the cosmology.
