论文摘要
我们研究了从耦合到Higgs玻色子(“ Loryons”)对Electroweak相变的BSM颗粒的影响。 BSM Loryons的存在意味着在标准模型的有效理论中,必须非线性地实现电子对称性。由于根据定义,Loryons与Higgs具有显着的耦合,因此预计它们将对HIGGS有效潜力产生重大影响,从而对Higgs产生显着影响,从而对Higgs产生显着影响。我们表明,在当前实验和理论约束下可行的BSM Loryon参数空间与预测强一级相变的参数空间重叠。与非洛里子相比,Loryons具有强大一阶相变的参数空间的部分允许参数空间明显更大。
We study the effect of BSM particles receiving most of their mass from their coupling to the Higgs boson ("Loryons") on the electroweak phase transition. The existence of BSM Loryons would imply that electroweak symmetry must be non-linearly realized in the effective theory of the Standard Model. Since, by definition, Loryons have a significant coupling to the Higgs, they are expected to have a significant effect on the Higgs effective potential and thereby the electroweak phase transition. We show that the BSM Loryon parameter space viable under current experimental and theoretical constraints overlaps heavily with the parameter space in which a strongly first-order phase transition is predicted. The portion of the experimentally allowed parameter space which gives a strongly first-order phase transition is significantly larger for Loryons as compared to non-Loryons.
