We provide an asymptotically safe Pati-Salam embedding of the standard model. Safety is achieved by adding to the theory gauged vectorlike fermions and by employing recently developed large number-offlavor techniques and results. We show that the gauge, scalar quartic and Yukawa couplings achieve an interacting ultraviolet fixed point below the Planck scale. The minimal model is a relevant example of a standard model extension in which unification of all type of couplings occurs because of a dynamical principle, i.e., the presence of an ultraviolet fixed point. This extension differs from the usual grand unified theories scenario in which only gauge couplings unify and become free with the remaining couplings left unsafe. We find renormalization group flow solutions that match the standard model couplings values at low energies allowing for realistic safe extensions of the standard model.

“…In a recent work we looked at the possibility of high scale boundary conditions arising in the complex singlet extension of the SM [3]. This was motivated in part by the very small value of both the SM Higgs quartic coupling λ and its β function β λ at the Planck scale M Pl .…”

We investigate high scale boundary conditions on the quartic Higgs couplings and their β functions in the type-II two Higgs doublet model and the inert doublet model. These conditions are associated with two possible UV physics scenarios: the multiple point principle, in which the potential exhibits a second minimum at M Pl , and asymptotic safety, where the scalar couplings run toward an interacting UV fixed point at high scales. We employ a renormalization group running at two loops and apply theoretical and experimental constraints to their parameter spaces. We find neither model can simultaneously accommodate the multiple point principle while also providing realistic masses for both the Higgs and the top quark. However, we do find regions of parameter space compatible with asymptotic safety.
