Thermal Metastable Strings in One-Scale Models and Gravitational Waves
Arturo de Giorgi, James Ingoldby, Valentin V. Khoze +1
Metastable cosmic strings provide a cosmological interpretation of the nanohertz stochastic gravitational wave background reported by Pulsar Timing Array (PTA) experiments. We revi…
Monopoles at Future Neutrino Detectors
Pablo M. Candela, Valentin V. Khoze, Jessica Turner
We investigate the potential of future neutrino experiments, DUNE and Hyper-Kamiokande, to probe magnetic monopoles via Callan-Rubakov (CR) processes. We consider both relativistic…
Probing the Cosmic Neutrino Background and New Physics with TeV-Scale Astrophysical Neutrinos
Jack Franklin, Ivan Martinez-Soler, Yuber F. Perez-Gonzalez +1
We use recent evidence of TeV neutrino events from the most significant astrophysical sources detected by IceCube -- NGC 1068, TXS 0506+056, PKS 1424+240 -- to constrain the local…
Hot Leptogenesis
Michael J. Baker, Ansh Bhatnagar, Djuna Croon +1
We investigate a class of leptogenesis scenarios in which the sector containing the lightest right-handed neutrino establishes kinetic equilibrium at a temperature $T_{N_1} > T_\te…
Thermal pressure on ultrarelativistic bubbles from a semiclassical formalism
Andrew J. Long, Jessica Turner
We study a planar bubble wall that is traveling at an ultrarelativistic speed through a thermal plasma. This situation may arise during a first-order electroweak phase transition i…
ALP Anarchy
Francesca Chadha-Day, James Maxwell, Jessica Turner
String theory models generically predict the existence of multiple axion-like particle (ALP) fields, yet the majority of both theoretical and experimental works have assumed only o…
