High Energy Physics Seminar
https://caltech.zoom.us/j/9399674944 Zoom meeting ID: 939 967 4944.
In this talk, I will briefly review the naturalness as guideline for model building. I will mostly focus on the phenomenology of composite Higgs models under broad assumption of partial compositeness and Higgs boson as the pseudo-Nambu-Goldstone boson. I will highlight the importance of symmetry selection rules in this scenario and further discuss about the possibility of transverse gauge boson as part of the strong dynamics. Last but not least, I will briefly discuss about the universal relationship between the Higgs couplings predicted by the non-linearized symmetry and their phenomenological relevance in the future lepton colliders.
