论文摘要
在Seesaw机制中，如果右手（RH）中微子质量是由$ u（1）$对称性破裂动态生成的，则由宇宙弦乐网络采购的随机重力波背景（SGWB）可能是潜在的卵生生成探针。我们表明，可以通过GW探测器以及下一代中微子beta Double beta衰减（$ 0M NEM NEM NETBETA）实验在辅助方式中探索促进Lepton不对称产生的瘦素发生机制。我们推断为成功的瘦素发生，对$ f-ω_ {\ rm gw} h^2 $平面的排除限制也对应于$ | m_ {ββ} | -m_1 $平面上的排除。我们考虑正常的光中微子质量排序，并讨论最近的Nanograv Pulsar时正时数据（如果解释为GW信号）如何在95 $ \％$ cl时与潜在的发现或$ 0 NULL信号相关。
In seesaw mechanism, if right handed (RH) neutrino masses are generated dynamically by a gauged $U(1)$ symmetry breaking, a stochastic gravitational wave background (SGWB) sourced by a cosmic string network could be a potential probe of leptogenesis. We show that the leptogenesis mechanism that facilitates the dominant production of lepton asymmetry via the quantum effects of right-handed neutrinos in gravitational background, can be probed by GW detectors as well as next-generation neutrinoless double beta decay ($0νββ$) experiments in a complementary way. We infer that for a successful leptogenesis, an exclusion limit on $f-Ω_{\rm GW}h^2$ plane would correspond to an exclusion on the $|m_{ββ}|-m_1$ plane as well. We consider a normal light neutrino mass ordering and discuss how recent NANOGrav pulsar timing data (if interpreted as GW signal) e.g., at 95$\%$ CL, would correlate with the potential discovery or null signal in $0νββ$ decay experiments.
