报告摘要：介绍引出复合希格斯模型的基本概念，主要着眼于它比起标准模型的希格斯而言有什么好处。特别地，我们将回顾相关的动力学，从格点的研究中得到一些启发。后者有助于理解现在和未来的对撞机实验在发现希格斯的复合性方面可以扮演什么样的角色。最后还会讨论在对撞机上会有什么样的可能信号：希格斯的耦合与标准模型的偏离，以及新的共振态的发现。

I will introduce the basic notions leading to the idea of a composite Higgs model, focusing on the advantages over the Standard Model Higgs sector. In particular, the role of the underlying dynamics will be reviewed, in light of the input that Lattice studies can give. The latter are crucial in order to understand the role current and future colliders can play in discovering the Higgs compositeness. I will finally discuss the main collider smoking guns: deviations in the Higgs couplings and discovery of new resonances.

Prof. Giacomo Cacciapaglia graduated from Pisa University in Italy, and obtained his PhD from the Scuola Normale Superiore in Pisa in 2003. After one postodoc at Cornell University and one in the University of California Davis in the USA, he obtained a permanent researcher position at CNRS in France in 2008. He has now a senior researcher position (equivalent to professorship) in Lyon, France. He is an expert in composite Higgs dynamics, extra-dimensional models and collider phenomenology.
