论文摘要
左右对称模型（LRSM）是一个充分动机的框架，可恢复奇偶校验并在TEV尺度上或更高版本的微小中微子质量中实施Seesaw机制，并且在高能和高精度边界上都具有非常丰富的现象学。在本文中，我们检查了最小版本的LRSM版本中的相变和产生的重力波（GWS）。考虑到LRSM上的所有理论和实验约束，我们在将来的实验中确定具有强大一阶相变和可检测GW的参数区域。事实证明，在参数空间的一个较大区域中，可以在相转换中以$ 10^{ - 17} $的强度在0.1至10 Hz的频率下生成$ 10^{ - 17} $的强度，这可以由BBO和DECTIGO检测到。此外，LRSM中的GWS偏爱相对较轻的$ su（2）_r $ - 破坏标量$ H_3^0 $，这在很大程度上与直接搜索在高富集船上的长期寿命中性标量的直接搜索。发现LRSM中的其他重型标量和右手中微子也对相变中GW信号产生起重要作用。
The left-right symmetric model (LRSM) is a well-motivated framework to restore parity and implement seesaw mechanisms for the tiny neutrino masses at or above the TeV-scale, and has a very rich phenomenology at both the high-energy and high-precision frontiers. In this paper we examine the phase transition and resultant gravitational waves (GWs) in the minimal version of LRSM. Taking into account all the theoretical and experimental constraints on LRSM, we identify the parameter regions with strong first-order phase transition and detectable GWs in the future experiments. It turns out in a sizeable region of the parameter space, GWs can be generated in the phase transition with the strength of $10^{-17}$ to $10^{-12}$ at the frequency of 0.1 to 10 Hz, which can be detected by BBO and DECIGO. Furthermore, GWs in the LRSM favor a relatively light $SU(2)_R$-breaking scalar $H_3^0$, which is largely complementary to the direct searches of a long-lived neutral scalar at the high-energy colliders. It is found that the other heavy scalars and the right-handed neutrinos in the LRSM also play an important part for GW signal production in the phase transition.
