Metastable Strings and Gravitational Waves in One-Scale Models
James Ingoldby, Valentin V. Khoze, Jessica Turner
Metastable cosmic strings provide a minimal and predictive origin for the stochastic gravitational-wave background reported by Pulsar Timing Array experiments. We analyse this poss…
The Good Qualities of the Weak Axion
Giacomo Cacciapaglia, Francesco Sannino, Jessica Turner
The presence of a topological susceptibility in the electroweak sector of the Standard Model motivates the existence of a good quality weak axion , associated with the spontan…
Hiding in Plain Sight, the electroweak
Giacomo Cacciapaglia, Francesco Sannino, Jessica Turner
The presence of a topological susceptibility in the electroweak sector of the Standard Model implies the existence of a pseudoscalar state in the spectrum, . We show that, wit…
Baryogenesis via Asymmetric Evaporation of Primordial Black Holes
Joaquim Iguaz Juan, Yuber F. Perez-Gonzalez, Jessica Turner
We revisit baryogenesis from the asymmetric evaporation of light primordial black holes, focusing on scenarios where gravitational effects induce a matter antimatter asymmetry. In…
