Torsion at different scales: from materials to the Universe

NE Mavromatos, P Pais, A Iorio - Universe, 2023 - mdpi.com
The concept of torsion in geometry, although known for a long time, has not gained
considerable attention from the physics community until relatively recently, due to its diverse …

Effect of torsion on neutron star structure in Einstein-Cartan gravity

C Jockel, L Menger - Physical Review D, 2024 - APS
Einstein-Cartan gravity is a close historical sibling of general relativity that allows for
spacetime torsion. As a result, angular momentum couples to spacetime geometry in a …

[HTML][HTML] The impact of the X17 boson on particle physics anomalies: Muon anomalous magnetic moment, Lamb shift and W mass

A Capolupo, A Quaranta, R Serao - Physics of the Dark Universe, 2025 - Elsevier
We show that the X 17 vector boson, introduced to explain the 8 Be anomalous decay, could
play a role in the muon's (electron's) anomalous magnetic moment and the muonic Lamb …

Missing matter in galaxies as a neutrino mixing effect

A Capolupo, S Capozziello, G Pisacane… - arXiv preprint arXiv …, 2024 - arxiv.org
We show that, in the framework of quantum field theory in curved spacetime, the
semiclassical energy-momentum tensor of the neutrino flavor vacuum fulfills the equation of …

The impact of the X17 boson on particle physics anomalies: muon anomalous magnetic moment, Lamb shift, W mass and dark charges

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 …
