Description
Special classes of non-supersymmetric, strongly interacting gauge theories provide ultraviolet completions for new physics extensions of the Standard Model that offer potential solutions to key open problems in the energy frontier, including the absence of new physics signatures at energies just above the electroweak scale, the anomalously heavy mass of the top quark, the absence of new flavor changing neutral current interactions, and the origin of dark matter. The non-perturbative nature of these theories makes lattice field theory the natural tool for computing the associated physical observables. After a brief overview of widely-studied proposals for strongly coupled theories in the context of beyond the Standard Model physics, in this talk, I focus on Higgs compositeness and top partial compositeness. Primarily, I discuss the Sp(4) gauge theory with matter consisting of two fundamental and three antisymmetric fermions, detailing its motivations as a template for this class of models. I present recent results from the TELOS collaboration on the mass spectrum of the model, emphasizing methodological advances that have broader applicability to lattice QCD studies. Finally, I discuss finite-temperature calculations in Sp(4) gauge theories with and without fermionic matter, and the potential relevance of associated phase transitions as sources of a stochastic relic density of gravitational waves.
