Gravitational dark matter from minimal preheating

Journal of High Energy Physics
Following our previous work, we continue to explore gravitational dark matter production during the minimal preheating caused by inflaton self-resonance.

Tests of fundamental physics with cosmological observables

Questa tesi indaga l'interazione tra fisica fondamentale e osservabili cosmologiche, offrendo un esame completo di come i dati cosmologici all'avanguardia possano vincolare estensioni delle attuali teorie.

Dark matter phenomenology and radiative neutrino masses in a singlet-doublet scotogenic model. A Markov Chain Monte Carlo Approach to Parameter Space Constraints and Phenomenological Predictions in the T1‐2A Model.

In this study, we explore the phenomenology of dark matter and radiative neutrino masses within the singlet-doublet scotogenic model, focusing specifically on the T1-2A topology.

Ultra-high frequency gravitational waves from scattering, Bremsstrahlung and decay during reheating

Journal of High Energy Physics
We investigate ultra-high frequency gravitational waves (GWs) from gravitons generated during inflationary reheating. Specifically, we study inflaton scattering with its decay product, where the couplings involved in this 2 → 2 scattering are the same as

Gravitational production of heavy particles during and after inflation

Journal of High Energy Physics
We investigate the gravitational production of a scalar field χ with a mass exceeding the Hubble scale during inflation m χ ≳ H I , employing both analytical and numerical approaches.
