We review the landscape of QCD axion models. Theoretical constructions that extend the
window for the axion mass and couplings beyond conventional regions are highlighted and …

We revisit the physics of neutrino magnetic moments, focusing in particular on the case
where the right-handed, or sterile, neutrinos are heavier (up to several MeV) than the left …

We argue that the interpretation in terms of solar axions of the recent XENON1T excess is
not tenable when confronted with astrophysical observations of stellar evolution. We discuss …

Elastic neutrino-electron scattering represents a powerful tool to investigate key neutrino
properties. In view of the recent results released by the LUX-ZEPLIN collaboration, we …

The XENON1T collaboration recently reported an excess in electron recoil events in the
energy range between 1–7 keV. This excess could be understood to originate from the …

A bstract In the early universe, Dirac neutrino magnetic moments due to their chirality-
flipping nature could lead to thermal production of right-handed neutrinos, which would …

In this paper, we find that a magnetic transition dipole moment between tau and sterile
neutrinos can account for the XENON1T excess events. Unlike the ordinary neutrino dipole …

The detection potential of the active neutrino magnetic moment (ν a MM) and the active
sterile transition magnetic moment (ν s MM) in the solar neutrino CE ν NS process from …

A bstract The XENON1T collaboration reported an excess of the low-energy electron recoil
events between 1 and 7 keV. We explore the possibility to explain such an anomaly by the …

We study the impact of neutrino magnetic moments on astrophysical neutrinos, in particular
supernova neutrinos and ultra-high energy neutrinos from extragalactic sources. We show …
