论文摘要
在通货膨胀宇宙学和粒子物理现象学的成功建立模型中，自发断裂对称对称性已被广泛利用。共形大统一理论（CGUT）通货膨胀提供了与Starobinsky和Higgs通货膨胀相同的标量倾斜度和张量与量表比。此外，它可以预测质子寿命与当前的实验结合兼容。在本文中，我们扩展了CGUT，以说明暗物质的产生和标准模型的再加热。为此，我们引入了一个直接耦合到充气量的隐藏扇区，而可见扇区的重新加热是通过黑暗颗粒和希格斯玻色子之间的门户耦合来实现的。黑暗颗粒和希格斯玻色子的质量和相互作用取决于加速器的保形电位和非逐渐变化的VEV的形式。我们在模型的参数空间中提供基准点，从而使观察到的暗物质遗物密度和与大爆炸核合成兼容的温度加热。
Spontaneous breaking of conformal symmetry has been widely exploited in successful model building of both inflationary cosmology and particle physics phenomenology. Conformal Grand Unified Theory (CGUT) inflation provides the same scalar tilt and tensor-to-scalar ratio as of Starobinsky and Higgs inflation. Moreover, it predicts a proton life time compatible with the current experimental bound. In this paper, we extend CGUT to account for the production of dark matter and the reheating of the Standard Model. To this end, we introduce a hidden sector directly coupled to the inflaton, whereas the reheating of the visible sector is realized through a portal coupling between the dark particles and the Higgs boson. The masses and interactions of the dark particles and the Higgs boson are determined by the form of the conformal potential and the non-vanishing VEV of the inflaton. We provide benchmark points in the parameter space of the model that give the observed dark matter relic density and reheating temperatures compatible with the Big Bang nucleosynthesis.
