Model-Building Implications from Light Magnetic Monopoles: A Case Study of Flavour Deconstruction
Marko Pesut, Davide Racco, Yunlong Zhao
We highlight a generic connection between extensions of the Standard Model featuring low-scale semi-simple embeddings of and the phenomenology of light magneti…
Impact of Supercooling on Direct Searches for Dark Matter and Gravitational Wave Backgrounds
Davide Racco, Alfredo Stanzione
An interesting feature of a cosmological phase transition can be a stage of exponential expansion (supercooling). The modified expansion history and the entropy injection at reheat…
Understanding the Nature of Scalar-Induced Gravitational Waves
A. J. Iovino, G. Perna, D. Perrone +2
We offer a physical interpretation of the origin of the scalar-induced gravitational wave background, showing that it is mainly produced around the peaks of the scalar perturbation…
Probing Flavour Deconstruction via Primordial Gravitational Waves
Noemi Fabri, Gino Isidori, Davide Racco
We study the production of primordial gravitational waves (GWs) from first-order phase transitions (FOPTs) in extensions of the Standard Model based on Flavour Deconstruction (FD).…
Revisiting Isocurvature Bounds on the Minimal QCD Axion
Peter W. Graham, Davide Racco
The QCD axion has important connections to early universe cosmology. For example, it is often said that isocurvature limits rule out a combination of high axion decay constant, $f_…
Neutrino masses from large-scale structures: future sensitivity and theory dependence
Davide Racco, Pierre Zhang, Henry Zheng
In the incoming years, cosmological surveys aim at measuring the sum of neutrino masses , complementing the determination of their mass ordering from laboratory experiments.…
Gravitational Production of Heavy Particles during and after Inflation
Davide Racco, Sarunas Verner, Wei Xue
We investigate the gravitational production of a scalar field with a mass exceeding the Hubble scale during inflation , employing both analytical and numerical…
