Chiral Anomaly and Schwinger Effect in Non-Abelian Gauge Theories
Valerie Domcke, Yohei Ema, Kyohei Mukaida +1
We study the production of chiral fermions in a background of a strong non-abelian gauge field with a non-vanishing Chern-Pontryagin density. We discuss both pair production analog…
Freeze-in leptogenesis with 3 right-handed neutrinos
Michele Lucente, Asmaa Abada, Giorgio Arcadi +3
We provide the first systematic study of the viable parameter space for leptogenesis in the type-I seesaw model with three right-handed neutrinos whose Majorana masses lie below th…
Low-scale leptogenesis with three heavy neutrinos
Asmaa Abada, Giorgio Arcadi, Valerie Domcke +3
Leptogenesis induced by the oscillations of GeV-scale neutrinos provides a minimal and testable explanation of the baryon asymmetry of the Universe. In this work we extend previous…
Strong constraints on clustered primordial black holes as dark matter
Torsten Bringmann, Paul Frederik Depta, Valerie Domcke +1
The idea of dark matter in the form of primordial black holes has seen a recent revival triggered by the LIGO detection of gravitational waves from binary black hole mergers. In th…
Emerging chromo-natural inflation
Valerie Domcke, Ben Mares, Francesco Muia +1
The shift-symmetric coupling of a pseudo-scalar particle driving inflation to gauge fields provides a unique way of probing cosmic inflation. We show for an SU(2) gauge group how a…
Probing non-Gaussian Stochastic Gravitational Wave Backgrounds with LISA
Nicola Bartolo, Valerie Domcke, Daniel G. Figueroa +7
The stochastic gravitational wave background (SGWB) contains a wealth of information on astrophysical and cosmological processes. A major challenge of upcoming years will be to ext…
