Machine Learning for Multi-messenger Probes of New Physics and Cosmology: A Review and Perspective
Andrea Addazi, Konstantin Belotsky, Vitaly Beylin +18
The multi-messenger exploration of dark matter and physics beyond the Standard Model has emerged as a central direction in modern astro-particle physics, particularly following the…
Gravitational echoes of lepton number symmetry breaking with light and ultralight Majorons
Andrea Addazi, Antonino Marcianò, António P. Morais +3
We formulate a version of the low-scale Majoron model equipped with an inverse seesaw mechanism featuring lepton-number preserving dimension-6 operators in the scalar potential. Co…
Dark Energy and Neutrino Superfluids
Andrea Addazi, Salvatore Capozziello, Qingyu Gan +1
We show that the neutrino mass, the dark matter and the dark energy can be explained in a unified framework, postulating a new invisible Born-Infeld field, which we name "non-linea…
CDF II -mass anomaly faces first-order electroweak phase transition
Andrea Addazi, Antonino Marciano, António P. Morais +2
We suggest an appealing strategy to probe a large class of scenarios beyond the Standard Model simultaneously explaining the recent CDF II measurement of the boson mass and pre…
Cosmology from Strong Interactions
Andrea Addazi, Torbjörn Lundberg, Antonino Marcianò +2
The wealth of theoretical and phenomenological information about Quantum Chromodynamics at short and long distances collected so far in major collider measurements has profound imp…
Topological portals from matter to antimatter
Andrea Addazi
We discuss possibilities of generating a Majorana mass for the neutron from topological quantum gravity effects which survive at mesoscopic scales from decoherence. We show how vir…

A. Addazi, J. Alvarez-Muniz, R. Alves Batista +157
The exploration of the universe has recently entered a new era thanks to the multi-messenger paradigm, characterized by a continuous increase in the quantity and quality of experim…
QCD surprises: strong CP problem, neutrino mass, Dark Matter and Dark Energy
Andrea Addazi, Antonino Marciano, Roman Pasechnik +1
An unexpected explanation for neutrino mass, Dark Matter (DM) and Dark Energy (DE) from genuine Quantum Chromodynamics (QCD) of the Standard Model (SM) is proposed here, while the…
NANOGrav results and Dark First Order Phase Transitions
Andrea Addazi, Yi-Fu Cai, Qingyu Gan +2
The recent NANOGrav evidence of a common-source stochastic background provides a hint to Gravitational Waves (GW) radiation from the Early Universe. We show that this result can be…
Gravitational footprints of massive neutrinos and lepton number breaking
Andrea Addazi, Antonino Marcianò, António P. Morais +3
We investigate the production of primordial Gravitational Waves (GWs) arising from First Order Phase Transitions (FOPTs) associated to neutrino mass generation in the context of ty…
Tests of Pauli Exclusion Principle Violations from Non-commutative quantum gravity
Andrea Addazi, Rita Bernabei
We review the main recent progresses in non-commutative space-time phenomenology in underground experiments. A popular model of non-commutative space-time is -Poincaré model, ba…
A modern guide to {\rm }-Poincaré
A. Addazi, A. Marciano
Motivated by the recent interest in underground experiments phenomenology, we review the main aspects of one specific non-commutative space-time model, based on the Groenewold-Moya…
Probing Trans-electroweak First Order Phase Transitions from Gravitational Waves
Andrea Addazi, Antonino Marciano, Roman Pasechnik
We propose direct tests of very high energy first-order phase transitions, which are elusive to collider physics, deploying the gravitational waves measurements. We show that first…
