TL;DR
The paper proposes that the XENON1T excess could be explained by solar neutrinos with transition magnetic moments, fitting within current experimental limits and considering potential tritium contamination.
Contribution
It introduces a formalism linking neutrino transition magnetic moments to XENON1T signals, providing a novel interpretation consistent with existing constraints.
Findings
XENON1T excess compatible with neutrino magnetic moments
Transition magnetic moments within current experimental bounds
Possible influence of tritium contamination on results
Abstract
The recent puzzling results of the XENON1T collaboration at few keV electronic recoils could be due to the scattering of solar neutrinos endowed with finite Majorana transition magnetic moments (TMMs). Within such general formalism, we find that the observed excess in the XENON1T data agrees well with this interpretation. The required TMM strengths lie within the limits set by current experiments, such as Borexino, specially when one takes into account a possible tritium contamination.
