Description
Neutrinos are among the most mysterious particles in the Standard Model, and their possible electromagnetic properties offer a compelling window into physics beyond the standard framework. Features such as a non-zero magnetic moment, a finite charge radius, or a tiny electric charge (millicharge) are not only theoretically intriguing, but also experimentally accessible through precision measurements at low energies.
This talk explores recent progress in probing these properties using two complementary approaches: coherent elastic neutrino-nucleus scattering (CEvNS) and neutrino-electron scattering from various neutrino sources. On the CEvNS side, I will present results from recent reactor- and accelerator-based experiments, including data from the COHERENT collaboration [1] and new measurements at nuclear power facilities using high-purity germanium detectors, such as CONUS+ [2].
In parallel, I will discuss how direct dark matter detection experiments, originally designed for WIMP searches, have become powerful tools for neutrino physics [3,4]. Their sensitivity to solar neutrinos interacting with both atomic electrons and nuclei enables them to set competitive constraints on neutrino electromagnetic couplings. Notably, the complementarity of these approaches provides a unique opportunity to explore possible flavor structures within neutrino electromagnetic scenarios.
Taken together, these diverse experimental results allow us to place stringent, model-independent bounds on neutrino electromagnetic properties and point toward new avenues in the quest for physics beyond the Standard Model.
