A post-inflationary kinetic axion
Enrico Morgante, Riccardo Natale
We present a novel realization of axion kinetic misalignment, triggered by a Hubble-induced phase transition during a post-inflationary stiff (kination) era. A negative Ricci scala…
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…
Reconstructing Primordial Curvature Perturbations via Scalar-Induced Gravitational Waves with LISA
Jonas El Gammal, Aya Ghaleb, Gabriele Franciolini +17
Many early universe scenarios predict an enhancement of scalar perturbations at scales currently unconstrained by cosmological probes. These perturbations source gravitational wave…
