Description
The structures of Yukawa matrices have been a long-standing mystery of the Standard Model. One possible solution is assuming an abelian $U(1)_F$ flavor symmetry and introducing a small parameter $\epsilon$ through the Froggatt-Nielson mechanism. In this talk, I will show how to realize the Froggatt-Nielson mechanism within the framework of composite Higgs models. In this type of model, both the flavor structure and electroweak symmetry breaking originate from TeV-scale strong dynamics. The flavon field arises as a pseudo-Nambu-Goldstone bosons of the broken symmetry and the Froggatt-Nielson fields (vector-like fermions) arise as composite resonances (hadrons) of the strong dynamics.
