Many extensions of the Standard Model include a new $U(1)$ gauge group thatis broken spontaneously at a scale much above TeV. If a $U(1)$-breaking phasetransition occurs at nucleation temperature of $O(100)$-$O(1000)$~TeV, it cangenerate stochastic gravitational waves in $O(10)$-$O(100)$ Hz range if$\beta_{\rm n}/H_{\rm n}=1000$, which can be detected by ground-baseddetectors. Meanwhile, supersymmetry (SUSY) may play a crucial role in thedynamics of such high-scale $U(1)$ gauge symmetry breaking, because SUSYbreaking scale is expected to be at TeV to solve the hierarchy problem. In thispaper, we study the phase transition of $U(1)$ gauge symmetry breaking in aSUSY model in the SUSY limit. We consider a particular example, the minimalSUSY $U(1)_{B-L}$ model. We derive the finite temperature effective potentialof the model in the SUSY limit, study a $U(1)_{B-L}$-breaking phase transition,and estimate gravitational waves generated from it.
