Spin-dependent neutrino oscillations in torsion backgrounds: A quantum-field-theoretic analysis
Raoul Serao, Giuseppe De Maria, Simone Monda +2
We study neutrino mixing in a background with spacetime torsion within the quantum-field-theoretic formulation of flavor oscillations. Working in the Einstein--Cartan framework and…
The X17 Anomaly: Experimental Evidence and Theoretical Interpretations
Raoul Serao, Aniello Quaranta, Antonio Capolupo
This review summarizes the experimental evidence for the hypothetical X17 particle, examines the theoretical frameworks in which it can be accommodated, and discusses its potential…
A Breakdown Case Study of the Lindblad Approach via Entanglement and Purity
Raoul Serao, Aniello Quaranta, Antonio Capolupo +2
The Lindblad master equation is widely used to describe the reduced dynamics of open quantum systems under Markovian assumptions. Here, we investigate its ability to reproduce the…
Geometric Phases as Probes of Dark Sectors
Antonio Capolupo, Gabriele Pisacane, Raoul Serao
We review recent interferometric schemes designed to probe physics beyond the Standard Model through the detection of geometric phases. We discuss how interactions with hidden-sect…
Addressing Standard Model Tensions via X17 Vector Boson
Raoul Serao, Aniello Quaranta, Antonio Capolupo
We investigate the effects of introducing a new vector boson on existing discrepancies within the Standard Model. Our analysis highlights the potential of this particle to alleviat…
Particle Physics in Curved Spacetime and Dark Matter
Antonio Capolupo, Salvatore Capozziello, Gabriele Pisacane +1
We review recent results showing that, within the framework of quantum field theory in curved spacetime, the semiclassical energy-momentum tensor of the neutrino flavor vacuum fulf…
