Invisible decay of solar neutrinos at dark matter experiments
Martina Beccaria, Veronica Beligotti, Valentina De Romeri +4
The combination of the long baseline and characteristic energies of solar neutrinos offers an ideal framework to probe invisible neutrino decay. In this work we present the first c…
New light mediators and the neutrino fog: Implications from XENONnT nuclear recoil data
Valentina De Romeri, Anirban Majumdar, Dimitrios K. Papoulias +1
Current ton-scale, xenon-based dark matter (DM) direct detection experiments have now reached the sensitivity required to observe solar neutrinos, marking the onset of the so-calle…
Refined extraction of electroweak and nuclear parameters from germanium CENS data
Valentina De Romeri, Laura Duque, Dimitrios K. Papoulias +2
We present a combined analysis of recent CENS data on germanium from two complementary experiments: COHERENT, which uses neutrinos from pion decay at rest, and CONUS+, which det…
Sensitivity to sub-GeV dark matter in forthcoming spallation-source neutrino experiments
D. Aristizabal Sierra, V. De Romeri, D. K. Papoulias +1
Sub-GeV thermal dark matter weakly interacting with the Standard Model through vector-portal mediators provides a well-motivated and predictive framework that remains challenging t…
Axial-vector neutral-current measurements in coherent elastic neutrino-nucleus scattering experiments
D. Aristizabal Sierra, Pablo M. Candela, Valentina De Romeri +2
Coherent elastic neutrino-nucleus scattering (CENS) is predominantly governed by vector neutral-current interactions, with subleading contributions arising from the axial curre…
Testing light and heavy vector mediators with solar CENS measurements
Valentina De Romeri, Dimitrios K. Papoulias, Federica Pompa +2
The recent observation of coherent elastic neutrino-nucleus scattering from solar B neutrinos in dark matter direct detection experiments has inaugurated the \emph{neutrino fog…
