Concurrence Dynamics in Self-Gravitating Mixed Neutrinos
Raoul Serao, Gianpaolo Torre, Antonio Capolupo
We study the entanglement generated by Newtonian self-gravity in a two-particle system of mixed neutrinos and quantify it by means of the concurrence. Starting from the gravitation…
Solar capture and annihilation of fermionic and scalar dark matter motivated by the LUX-ZEPLIN high-recoil candidate
Antonio Capolupo, Gabriele Pisacane, Raoul Serao
Motivated by the LUX-ZEPLIN high-energy nuclear-recoil candidate, we ask whether solar evolution can distinguish dark-matter models that are degenerate in their leading xenon recoi…
Electron and Muon Constraints on Light Vector Bosons: Dark Photons and the Boson
Raoul Serao, Antonio Capolupo
We combine the current experimental muon world average, which incorporates the final Fermilab result, with the latest electron determinations based on cesium and rubidi…
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…
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…
Quantum Information Meets High-Energy Physics: Probing Neutrinos and Beyond
Raoul Serao, Gianpaolo Torre, Antonio Capolupo
This review explores the interplay between quantum information theory and high-energy physics, emphasizing how decoherence effects and unconventional neutrino oscillation patterns…
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…
Single arm interferometry to probe the scalar field dark matter
Antonio Capolupo, Gabriele Pisacane, Aniello Quaranta +1
We analyse the interaction of photons with a scalar dark matter field ϕand we propose to use a single arm interferometer to reveal this interaction and constrain the parameters of…
Dark matter induced by neutrino mixing and flavor vacuum condensate probed by neutrino capture on tritium
Antonio Capolupo, Simone Monda, Gabriele Pisacane +2
We show that experiments designed to capture low energy neutrinos, like PTOLEMY are sensitive to the specific neutrino model. In particular, they might show a signature of the cond…
Exploring X17 and dark charges in the context of Standard Model tensions
Antonio Capolupo, Aniello Quaranta, Raoul Serao
We report on recent results, according to which the hyphothetical X17 boson could affect the muon g-2 anomaly and the Lamb Shift. Moreover by considering the kinetic mixing between…
The impact of the X17 boson on particle physics anomalies: muon anomalous magnetic moment, Lamb shift, W mass and dark charges
Antonio Capolupo, Aniello Quaranta, Raoul Serao
We show that the X17 vector boson, introduced to explain the ^8 Be anomalous decay, could play a crucial role in the explanation of the muon's (electron's) anomalous magnetic momen…
Quantum Field Theory of neutrino mixing in spacetimes with torsion
Antonio Capolupo, Giuseppe De Maria, Simone Monda +2
In the framework of quantum field theory, we analyze the neutrino oscillations in the presence of a torsion background. We consider the Einstein-Cartan theory and we study the case…
Phenomenological implications of nonlocal quantum electrodynamics

A nonlocal theory of fermion mixing
Antonio Capolupo, Aniello Quaranta, Raoul Serao
We study a nonlocal generalization of two flavor fermion mixing and compute the transition probability by means of the path integral formalism. In our treatment, we delocalize only…
