Dynamically vanishing Dirac neutrino mass from quantum scale symmetry
Astrid Eichhorn, Aaron Held
We present a mechanism which drives Dirac neutrino masses to tiny values along the Renormalization Group flow, starting from an asymptotically safe ultraviolet completion of the th…
Quark masses and mixings in minimally parameterized UV completions of the Standard Model
Reinhard Alkofer, Astrid Eichhorn, Aaron Held +3
We explore a simple parameterization of new physics that results in an ultraviolet complete gauge-quark sector of the Standard Model. Specifically, we add an antiscreening contribu…
Higgs stability-bound and fermionic dark matter
Aaron Held, René Sondenheimer
Higgs-portal interactions of fermionic dark matter -- in contrast to fermions coupled via Yukawa interactions -- can have a stabilizing effect on the standard-model Higgs potential…
Asymptotic safety in the dark
Astrid Eichhorn, Aaron Held, Peter Vander Griend
We explore the Renormalization Group flow of massive uncharged fermions -- a candidate for dark matter -- coupled to a scalar field through a Higgs portal. We find that fermionic f…
