【摘要】

In composite Higgs models, the Higgs is realized as a pseudo-Nambu-Goldstone boson which is a bound state of underlying fermions. Many UV embeddings of composite Higgs models predict additional potentially light (pNGB) resonances, as well as Dirac-fermion partners of the top quark at the TeV scale. In the first part of this talk we survey the pNGB sectors of UV embedded composite Higgs models with SU(4)/Sp(4) , SU(5)/SO(5), and SU(4)xSU(4)/SU(4) symmetry breaking patterns, and we summarize searches and experimental bounds. In the second part, we discuss the rich phenomenology of top partners in these model classes. We show that “exotic" decays of top partners into 3rd generation quarks and pNGBs commonly occur and discuss several examples.
