Mårten Bertenstam, Marco Finetti, António P. Morais, Roman Pasechnik, Johan Rathsman

AI总结:

本文研究可解释中微子质量的最小轻子夸克模型中一阶相变产生的引力波信号,发现mHz–0.1 Hz频段的可探测信号对应颜色恢复和约1.5 TeV的轻子夸克质量,并首次应用了维度约化相变分析工具Dratopi。

摘要:

我们研究标准模型的最小轻子夸克扩展中的一阶相变及由此产生的随机引力波谱,该模型能够解释活跃中微子振荡数据,同时满足当前的味物理约束。该模型展现出多样的相变模式,包括早期宇宙中的颜色对称性破缺情形。模型参数与引力波信号之间的强关联为未来实验(如LISA、BBO和DECIGO)提供了可检验的预言。具体而言,在mHz–0.1 Hz频率范围内的可探测信号具有颜色恢复特征,且轻子夸克质量接近1.5 TeV。通过本文,我们还首次在文献中应用了Dratopi。这是一个即将发布的相变分析工具,采用维度约化形式,将DRalgo包与Python以及略微修改的CosmoTransitions版本进行接口连接。

英文摘要:

We study the first-order phase transitions and the emerging stochastic gravitational wave spectrum in a minimal leptoquark extension of the Standard Model that explains active neutrino oscillation data while satisfying current flavor physics constraints. This model exhibits diverse phase transition patterns, including color symmetry-breaking scenarios in the early Universe. Strong correlations between model parameters and gravitational-wave signals yield testable predictions for future experiments such as LISA, BBO, and DECIGO. Specifically, a detectable signal in the mHz$\unicode{x2013}$0.1~Hz frequency range features color-restoration and leptoquark masses near $1.5~\mathrm{TeV}$. With this article, we also present the first application in the literature of \texttt{Dratopi}. This is a soon-to-be-released tool for phase transition analysis using the dimensional reduction formalism, that interfaces the \texttt{DRalgo} package with \texttt{Python} and a slightly modified version of \texttt{CosmoTransitions}.
