LHC上的量子色动力学研究
Studies of Quantum Chromodynamics at the LHC
摘要:
强子-强子碰撞数据的成功描述需要对量子色动力学有深刻的理解。不可避免的是,强相互作用现象的复杂性需要使用各种各样的理论技术-从微扰截面计算到独特的强子最终状态的建模。加上LHC第一个运行期的实验提供的前所未有的精确数据,可以建立TeV级强子-强子碰撞物理学的坚实基础,从而发现希格斯玻色子,这对于估计寻找新现象的背景至关重要。这一章的研究量子色动力学在大型强子对撞机是最近的一本书的一部分,结果的大型强子对撞机运行1,并提出了先进的理论方法并排与相关的关键测量在一个综合的方法。
英文摘要:
A successful description of hadron-hadron collision data demands a profound understanding of quantum chromodynamics. Inevitably, the complexity of strong-interaction phenomena requires the use of a large variety of theoretical techniques -- from perturbative cross-section calculations up to the modelling of exclusive hadronic final states. Together with the unprecedented precision of the data provided by the experiments in the first running period of the LHC, a solid foundation of hadron-hadron collision physics at the TeV scale could be established that allowed the discovery of the Higgs boson and that is vital for estimating the background in searches for new phenomena. This chapter on studies of quantum chromodynamics at the LHC is part of a recent book on the results of LHC Run 1 and presents the advances in theoretical methods side-by-side with related key measurements in an integrated approach.
