Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Tatsuya Hayashi, Shigeki Matsumoto, Yuki Watanabe, Tsutomu T. Yanagida, | Summary: The new gauge boson introduced in the minimal extension of the standard model (SM) by gauging the U(1)$_{rm B-L}$ symmetry plays the role of dark matter when the U(1)$_{rm B-L}$ gauge coupling is highly suppressed. This […]
