Description
We present evidence for excess low-energy interactions in the XENON1T detector and discuss possible interpretations. Using a 0.65 t yr exposure, we perform one of the most sensitive searches for solar axions, an enhanced neutrino magnetic moment using solar neutrinos, and bosonic dark matter. We observe an excess of low-energy (1—7 keV) events. A solar axion signal is favoured at 3.4σ over background, and the signal can also be explained by the beta-decay of tritium within the detector or by an enhanced neutrino magnetic moment.
