Quark and lepton mixing in the asymptotically safe Standard Model
Astrid Eichhorn, Zois Gyftopoulos, Aaron Held
The quark mixing (CKM) matrix is near-diagonal, whereas the lepton mixing (PMNS) matrix is not. We learn that both observations can generically be explained within an ultraviolet c…
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…
Grand unification and the Planck scale: An example of radiative symmetry breaking
Aaron Held, Jan Kwapisz, Lohan Sartore
Grand unification of gauge couplings and fermionic representations remains an appealing proposal to explain the seemingly coincidental structure of the Standard Model. However, to…
Quantum gravity phenomenology at the dawn of the multi-messenger era -- A review
A. Addazi, J. Alvarez-Muniz, R. Alves Batista +157
The exploration of the universe has recently entered a new era thanks to the multi-messenger paradigm, characterized by a continuous increase in the quantity and quality of experim…
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…
