Sp(2N) Gauge Theories and the Composite Higgs model

希格斯玻色子的发现于2012年7月得到证实，它负责导致W玻色子和Z玻色子获得质量的电弱相互作用的自发对称性破缺。希格斯粒子本身的质量为125GeV；这比标准模型的预期要低得多。这个问题的一个解决方案是，希格斯粒子不是基本粒子，而是由更小的成分组成(类似于强子由夸克组成的方式)。这可以被建模为耦合到费米子物质的Sp(2N)规范场。这个项目的目的是确定该理论的束缚态，它的低能行为，并在晶格上模拟该理论。后者的结果将被外推到连续统极限。

The Higgs boson, whose discovery was confirmed in July 2012, is responsible for the spontaneous symmetry breaking of the Electroweak interactions causing the W and Z bosons to acquire mass. The Higgs particle itself has a mass of 125 GeV; this is much lower than one would expect with the Standard Model. One resolution to this problem is that the Higgs is not a fundamental particle but is instead made of smaller constituents (similar to the way hadrons are made up of quarks). This can be modeled as an Sp(2N) gauge field that is coupled to fermionic matter. The aim of this project is to determine the bound states of the theory, its low energy behaviour and to simulate the theory on the lattice. The results from the latter will be extrapolated to the continuum limit.
