Féeton (B-L gauge boson) dark matter for the 511-keV gamma-ray excess and the prediction of low-energy neutrino flux* * Supported by the Talent Scientific Start-Up Project of China, the Natural Science Foundation of China (12175134, 12375101, 12090060, 12090064, 12247141), the SJTU Double First Class start-up fund(WF220442604), and the World Premier International Research Center Initiative (WPI Initiative), MEXT, Japan
The féeton is the gauge boson of the gauge theory. If the gauge coupling constant is extremely small, the féeton becomes a candidate for dark matter. We show that its decay to a pair of an electron and a positron explains the observed Galactic 511-keV gamma-ray excess in a consistent manner. This féeton dark matter decays mainly into pairs neutrino and anti-neutrino. Future low-energy experiments with improved directional capability will enable capturing these neutrino signals. The seesaw-motivated parameter space predicts a relatively short féeton lifetime that is comparable to the current cosmological constraint.
