Féeton ($B-L$ Gauge Boson) Dark Matter Testable in Future Direct Detection Experiments

Yu Cheng, Jie Sheng, Tsutomu T. Yanagida

In this paper, we revisit the féeton (gauge boson of $U(1{)}_{B-L}$ symmetry) dark matter scenario, and first point out the $U(1)$ gauge symmetry can be a linear combination of the $…
