Recently there has been revival of interest in partially composite Higgs models, where electroweak symmetry breaking is dynamically induced, and the Higgs boson is a mixture of a composite and an elementary state. While the Goldstone nature of the composite sector explains the lightness of the Higgs, the elementary scalars provide an UV completion for the SM fermion mass generation via...

Twin Higgs (TH) models explain the absence of new colored particles responsible for natural electroweak symmetry breaking. All known ultraviolet completions of TH models require some non-perturbative dynamics below the Planck scale. A new type of supersymmetric Twin Higgs model is presented in which the TH mechanism is introduced by a new asymptotically free gauge symmetry. The model features...

Composite Higgs models are among the most promising alternatives to solve the hierarchy problem and provide a dynamical mechanism to break the electroweak symmetry. In this talk I will discuss some predictions of specific UV realizations of such scenario. I will analyze in particular the phenomenology of vector and scalar states in a SU(4)/Sp(4) symmetry breaking pattern, using lattice results...
