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…
