Symplectic gauge theories coupled to matter fields lead symmetry enhancement phenomena that have potential applications in such diverse contexts as composite Higgs, top partial compositeness, strongly interacting dark matter, and dilaton-Higgs models. These are also interesting on theoretical grounds, for example reference the approach large-$N$ limit. A particularly compelling research aim is determination of extent conformal window with symplectic groups different field content consisting...

Spectral densities encode non-perturbative information crucial in computing physical observables strongly coupled field theories. Using lattice gauge theory data, we perform a systematic study to demonstrate the potential of recent technological advances reconstruction spectral densities.

We measure the masses of pseudoscalar flavour-singlet meson states in $Sp(4)$ gauge theory coupled to two Dirac fermions transforming fundamental representation and three antisymmetric representation. This provides a compelling ultraviolet completion for minimal composite Higgs model implementing also partial compositeness top quark. The spectrum contains two, comparatively light, states, which mix with one another. One them is Nambu-Goldstone boson (in massless limit), whereas other...
The hypothesis that dark matter could be a bound state of strongly coupled non-Abelian gauge theory is theoretically appealing and has variety interesting phenomenological implications. In particular, an interpretation as the lightest glueball in spectrum Yang-Mills theory, possibly to visible sector only through gravitational interactions, been discussed quite extensively literature, but most previous work focused on SU(N) theories. this article, we consider alternative model, based...
We report progress on our lattice calculations for the mass spectra of low-lying composite states in Sp(4) gauge theory coupled to two and three flavors Dirac fermions transforming fundamental two-index antisymmetric representations, respectively. This provides an ultraviolet completion Higgs model with Goldstone modes SU(4)/Sp(4) coset partial compositeness generating top-quark mass. measure meson chimera baryon masses. These masses are crucial constructing model. In particular, important...
