Unveiling atomic electron motion effects in high energy collisions at NA64
Fernando Arias-Aragón, Giovanni Grilli di Cortona, Enrico Nardi
Atomic electron motion is responsible for well-studied effects observed in low-energy (MeV-scale) processes. Recently, interest in this phenomenon has also emerged within the high-…
Combined Evidence for the Boson After PADME Results on Resonant Production in Positron Annihilation
Fernando Arias-Aragón, Giovanni Grilli di Cortona, Enrico Nardi +1
The Positron Annihilation into Dark Matter Experiment at the Laboratori Nazionali di Frascati has reported an excess of final-state events from positron annihilation on fi…
Atoms as Electron Accelerators for New Physics Searches
Fernando Arias-Aragón, Giovanni Grilli di Cortona, Enrico Nardi +1
Due to Heisenberg's uncertainty principle, atomic electrons localized around the nucleus exhibit a characteristic momentum distribution that, in elements with high atomic number, r…
Dark sector searches with high-intensity positron beams in the CERN North Area
F. Arias-Aragón, L. Darmé, R. Gargiulo +6
Dark sector models present a rich phenomenology that requires high-intensity beams and precision detectors for thorough exploration. The NA62 experiment has already published sever…
Axion-induced pair production: a new strategy for axion detection
Fernando Arias-Aragón, Maurizio Giannotti, Giovanni Grilli di Cortona +1
We revisit and update the axion-induced pair production process in a nuclear electric field mediated by the axion-electron coupling, $a+{{}^{A}_{Z}X} \rightarrow {{}^{A}_{Z}X} + e^…
Neutrino Masses and Hubble Tension via a Majoron in MFV
Manuel González-López
The recent tension between local and early measurements of the Hubble constant can be explained in a particle physics context. A mechanism is presented where this tension is allevi…
