摘要:

在规范对称群$SU(3)_C\otimes{SU(2)_L}\otimes{U(1)_Y}\otimes{U(1)_{B-L}}$的基础上,引入了具有局域B-L规范对称性的SM的最小超对称扩张(B-LSSM).在这个模型中,我们研究了具有单圈零温有效势修正的Higgs质量。此外,还具体推导了与两个$U(1)_{B-L}$ Higgs单态有关的有限温度有效势。然后我们可以得到强一级相变产生的引力波。在B-LSSM中,引力波信号可以像$h^2Ω_{GW}\sim10^{-11}$一样强,这可能在未来的实验中被探测到。

英文摘要:

Based on the gauge symmetry group $SU(3)_C\otimes{SU(2)_L}\otimes{U(1)_Y}\otimes{U(1)_{B-L}}$, 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 $U(1)_{B-L}$ 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 $h^2Ω_{GW}\sim10^{-11}$, which may be detectable in the future experiments.
