Abstract

Based on the gauge symmetry group SU(3)CSU(2)LU(1)YU(1)BLSU(3)_C\otimes{SU(2)_L}\otimes{U(1)_Y}\otimes{U(1)_{B-L}}, the minimal supersymmetric extension of the SM with local B-L gauge symmetry(B-LSSM) has been introduced. In this model, we study the Higgs masses with the one-loop zero temperature effective potential corrections. Besides, the finite temperature effective potentials connected with two U(1)BLU(1)_{B-L} Higgs singlets are deduced specifically. Then we can obtain the gravitational wave spectrums generated from the strong first-order phase transition. In the B-LSSM, the gravitational wave signals can be as strong as h2ΩGW1011h^2\Omega_{GW}\sim10^{-11}, which may be detectable in the future experiments.
