Wash-in leptogenesis after axion inflation

Valerie Domcke, Kohei Kamada, Kyohei Mukaida +2

CP violation and the violation of baryon-minus-lepton number B-L do not necessarily have to occur simultaneously in order to accomplish successful leptogenesis. Instead, it suffice…

A new constraint on primordial lepton flavour asymmetries

Valerie Domcke, Kohei Kamada, Kyohei Mukaida +2

A chiral chemical potential present in the early universe can source helical hypermagnetic fields through the chiral plasma instability. If these hypermagnetic fields survive until…

Gravitational Waves from Current-Carrying Cosmic Strings

Pierre Auclair, Simone Blasi, Vedran Brdar +1

Cosmic strings are predicted by many Standard Model extensions involving the cosmological breaking of a symmetry with nontrivial first homotopy group and represent a potential sour…

Axion dark matter from frictional misalignment

Alexandros Papageorgiou, Pablo Quílez, Kai Schmitz

We study the impact of sphaleron-induced thermal friction on the axion dark-matter abundance due to the interaction of an axion-like particle (ALP) with a dark non-abelian gauge se…

Cosmology with the Laser Interferometer Space Antenna

Pierre Auclair, David Bacon, Tessa Baker +177

The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…

New Ideas in Baryogenesis: A Snowmass White Paper

Gilly Elor, Julia Harz, Seyda Ipek +21

The Standard Model of Particle Physics cannot explain the observed baryon asymmetry of the Universe. This observation is a clear sign of new physics beyond the Standard Model. Ther…
