126. Composite Higgs, ALPs, and partially composite tops

We present a class of models of electro-weak symmetry breaking based on strongly coupled gauge theories. We discuss the requirements imposed by flavor and CP violation on the strong dynamics. All these models give rise to an ALP that is an interesting target for searches at the high luminosity run of LHC. We present its effective lagrangian and some of the current bounds.

We present a UV-complete extension of the Standard Model based on the gauge group (SU(5)\times SU(3)c^{\prime}\times Sp(2){TC}^{\prime}\times SU(2)L\times U(1)_Y), which breaks in two steps to QCD and a technicolor sector. Three axions cancel the three (\theta)-terms. Small instantons from the confining (SU(3)_c^{\prime}) and (Sp(2){TC}^{\prime}) sectors generate axion potentials,...
