The devil in the transition: NLO nucleation and the particle physics behind the PTA signal
Cristina Puchades-Ibáñez, Pedro Schwaller
We quantify how the treatment of a strongly supercooled phase transition affects the particle-physics interpretation of a nanohertz gravitational-wave signal. For the classically c…
Beyond the Daisy Chain: Running and the 3D EFT View of Supercooled Phase Transitions
Martin Christiansen, Eric Madge, Cristina Puchades-Ibáñez +2
Pulsar timing arrays have recently observed a stochastic gravitational wave background at nano-Hertz frequencies. This raises the question whether the signal can be of primordial o…
ALP Production from Abelian Gauge Bosons: Beyond Hard Thermal Loops
Mathias Becker, Julia Harz, Enrico Morgante +2
Previous computations of feebly interacting particle production have encountered issues with unphysical (negative) interaction rates at soft momenta. We address this problem by stu…
Primordial gravitational waves in the nano-Hertz regime and PTA data -- towards solving the GW inverse problem
Eric Madge, Enrico Morgante, Cristina Puchades-Ibáñez +4
In recent years, several pulsar timing array collaborations have reported first hints for a stochastic gravitational wave background at nano-Hertz frequencies. Here we elaborate on…
