An additional U(1) gauge interaction is one of the promising extensions of the standard model of particle physics. Among others, the U(1)B–L gauge symmetry is particularly interesting because it addresses the origin of Majorana masses of right-handed neutrinos, which naturally leads to tiny light neutrino masses through the seesaw mechanism. We show that, based on the minimal U(1)B–L model, the symmetry breaking of the extra U(1) gauge symmetry with its minimal Higgs sector in the early universe can exhibit the first-order phase transition and hence generate a large enough amplitude of stochastic gravitational wave radiation that is detectable in future experiments.
