Probing super-heavy dark matter with ultra-high-energy gamma rays
Marco Chianese, Ninetta Saviano, Sara Cesare +4
We refine the constraints on the lifetime of decaying super-heavy dark matter particles (SHDM), with masses ranging from to GeV, by analyzing ultra-high-energy (UH…
Induced Gravitational Waves as Cosmic Tracers of Leptogenesis
Marco Chianese, Guillem Domènech, Theodoros Papanikolaou +2
We demonstrate that induced gravitational waves (IGWs) can naturally emerge within well-motivated realizations of thermal leptogenesis, thereby providing a possible observational h…
Neutrino Theory in the Precision Era
Asmaa Abada, Gabriela Barenboim, Toni Bertólez-Martínez +76
This document summarises discussions on future directions in theoretical neutrino physics, which are the outcome of a neutrino theory workshop held at CERN in February 2025. The st…
Impact of memory-burdened primordial black holes on high-scale leptogenesis
Roberta Calabrese, Marco Chianese, Ninetta Saviano
We explore the impact of the back-reaction of evaporation on the quantum state of Primordial Black Holes (PBHs), known as ``memory burden", on the baryon asymmetry production in th…
Probing flavored regimes of leptogenesis with gravitational waves from cosmic strings
Marco Chianese, Satyabrata Datta, Gennaro Miele +2
Cosmic strings radiate detectable gravitational waves in models featuring high-scale symmetry breaking, e.g., high-scale leptogenesis. In this Letter, for the first time, we show t…
Tomography of flavoured leptogenesis with primordial blue gravitational waves
Marco Chianese, Satyabrata Datta, Rome Samanta +1
We explore a scenario where an early epoch of matter domination is driven by the mass scale of the right-handed neutrinos, which also characterizes the different flavour regi…
