研究镜像标准模型扩展世界，发现强一级电弱相变可产生可探测引力波，且镜像粒子可能构成全部暗物质。
AI 中文摘要
我们研究了一个镜像标准模型世界，其中包含一个高尺度的标准模型副本，并包括一个与镜像希格斯粒子耦合的单态镜像标量扩展。在镜像希格斯与镜像单态标量的相互作用中，我们包含了维度为六的非重整化算符。我们检验了该镜像单态扩展世界的电弱相变，并表明该相变为强一级相变，其气泡碰撞可被LISA、BBO和DECIGO引力波实验探测到。我们还对镜像单态的丰度进行了粗略估计，并表明宇宙中的全部暗物质可能由镜像粒子和原子组成。
英文摘要
We study a mirror Standard Model world which contains a high scale duplicate of the Standard Model, and includes a singlet mirror scalar extension coupled to the mirror Higgs particle. Among the interactions of the mirror Higgs to the mirror singlet scalar, we include dimension-six non-renormalizable operators. We examine the electroweak phase transition of this mirror singlet extended world and we show that the phase transition is a strong first order phase transition, the bubble collision of which can be detectable by LISA, the BBO and the DECIGO gravitational wave experiments. We also provide a rough estimate of the abundance of the mirror singlet and we show that the whole dark matter in the Universe may be comprised by mirror particles and atoms.
