An EOS-Driven Extension of NSCool for Compact Star Cooling with Hadronic and Quark Degrees of Freedom
Federico Nola, Fernando Arias-Aragón
We present an EOS-driven extension of the NSCool thermal evolution code that enables complete tabulated equations of state to be treated within a single composition-based input str…
Core Composition Effects on the QCD Axion Mass Limit from Neutron Star Cooling
Fernando Arias-Aragón, Federico Nola
Neutron stars are very dense media in which axions may be produced. This has been used to set a limit on the QCD axion mass, usually under the assumption that only neutrons, proton…
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^…
Atoms as electron accelerators for measuring the hadrons cross section
Fernando Arias-Aragón, Luc Darmé, Giovanni Grilli di Cortona +1
The hadronic vacuum polarization contribution to can be determined via dispersive methods from hadrons data. We propose a novel approach to measure the hadro…
Production of dark sector particles via resonant positron annihilation on atomic electrons
Fernando Arias-Aragón, Luc Darmé, Giovanni Grilli di Cortona +1
Resonant positron annihilation on atomic electrons provides a powerful method to search for light new particles coupled to . Reliable estimates of production rates require…
New Directions for ALP Searches Combining Nuclear Reactors and Haloscopes
Fernando Arias-Aragón, Vedran Brdar, Jérémie Quevillon
In this work we propose reactoscope, a novel experimental setup for axion-like particle (ALP) searches. Nuclear reactors produce a copious number of photons, a fraction of which co…
Axion-like ALPs
Fernando Arias-Aragón, Jérémie Quevillon, Christopher Smith
The Effective Field Theory (EFT) Lagrangian for a generic axion-like particle (ALP) has many free parameters, and leaves quite some freedom for the expected phenomenology. In this…
Leptoquarks, axions and the unification of B, L, and Peccei-Quinn symmetries
Fernando Arias-Aragón, Christopher Smith
In this paper, axion models supplemented by leptoquarks and diquarks are systematically analyzed. Turning on some couplings to and among these latter states permits to unify the Pe…
Dynamical Minimal Flavour Violating Inverse Seesaw
Fernando Arias-Aragón, Enrique Fernández-Martínez, Manuel González-López +1
The Inverse Seesaw mechanism is dynamically realised within the Minimal Lepton Flavour Violation context. Lepton number, whose breaking is spontaneously realised, is generalised to…
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…
Production of Thermal Axions across the ElectroWeak Phase Transition
Fernando Arias-Aragon, Francesco D'Eramo, Ricardo Z. Ferreira +2
Light axions can potentially leave a cosmic background, just like neutrinos. We complete the study of thermal axion production across the electroweak scale by providing a smooth an…
Neutrino Masses and Hubble Tension via a Majoron in MFV
Fernando Arias-Aragon, Enrique Fernandez-Martinez, Manuel Gonzalez-Lopez +1
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…
Cosmic Imprints of XENON1T Axions
Fernando Arias-Aragon, Francesco D'Eramo, Ricardo Z. Ferreira +2
The recent electron recoil excess observed by XENON1T has a possible interpretation in terms of solar axions coupled to electrons. If such axions are still relativistic at recombin…
Data Driven Flavour Model
F. Arias-Aragon, C. Bouthelier-Madre, J. M. Cano +1
A bottom-up approach has been adopted to identify a flavour model that agrees with present experimental measurements. The charged fermion mass hierarchies suggest that only the top…
The Minimal Flavour Violating Axion
F. Arias-Aragon, L. Merlo
The solution to the Strong CP problem is analysed within the Minimal Flavour Violation (MFV) context. An Abelian factor of the complete flavour symmetry of the fermionic kinetic te…
