Probing a Light Scalar Boson with a few-MeV Proton Beam Deep Underground
Carlo Broggini, Giuseppe Di Carlo, Luca Di Luzio +2
We propose to investigate the production of a light scalar boson in low-energy proton-nucleus interactions using the 3.5 MV accelerator of the Bellotti Ion Beam Facility, locat…
Weak nuclear decays deep-underground as a probe of axion dark matter
Jorge Alda, Carlo Broggini, Giuseppe Di Carlo +4
We investigate the time modulation of weak nuclear decays as a method to probe axion dark matter. To this end, we develop a theoretical framework to compute the -dependence of w…
Catalogues of Cosmologically Self-Consistent Hadronic QCD Axion Models
Luca Di Luzio, Sebastian Hoof, Coenraad Marinissen +1
We extend the catalogue of "phenomenologically preferred" hadronic axion models to include heavy fermion representations associated with higher-dimensional decay operators. The lat…
Breakdown of chiral perturbation theory for the axion hot dark matter bound
Luca Di Luzio, Guido Martinelli, Gioacchino Piazza
We show that the commonly adopted hot dark matter (HDM) bound on the axion mass 1 eV is not reliable, since it is obtained by extrapolating the chiral expansion in a…
Selective enhancement of the QCD axion couplings
Luc Darmé, Luca Di Luzio, Maurizio Giannotti +1
We present a mechanism wherein the QCD axion coupling to nucleons, photons, or electrons, can be enhanced selectively without increasing the axion mass. We focus in particular on t…
Axion-mediated forces, CP violation and left-right interactions
Stefano Bertolini, Luca Di Luzio, Fabrizio Nesti
We compute the CP-violating (CPV) scalar axion coupling to nucleons in the framework of baryon chiral perturbation theory and we apply the results to the case of left-right symmetr…
Flavour Violating Axions
Luca Di Luzio
I review the physics case for flavour violating axions. In particular, I argue that relaxing the assumption of the universality of the Peccei-Quinn current opens up new pathways, i…
- mixing interplay with anomalies
Luca Di Luzio, Matthew Kirk, Alexander Lenz
After reviewing the theoretical uncertainties entering the Standard Model determination of the mass difference of the neutral - meson system, , we dis…
Gauge leptoquark as the origin of B-physics anomalies
Luca Di Luzio, Admir Greljo, Marco Nardecchia
The vector leptoquark representation, , was recently identified as an exceptional single mediator model to address experimental hints on lepton flavour universality…
