$Ψ$DM and the Bullet Cluster: Couple Inflaton to Higgs Field
Chia-Li Hsieh · arXiv (Cornell University) · 2016
Electroweak theory is extended to $SU_L(2)\times U_Y(1)\times U_ϕ(1)$, where $U_ϕ(1)$ comes from the coupling of inflaton field to Higgs field. There arises an extremely light boson, $Y_μ$. We resemble it as the wavelike dark matter, $Ψ$DM, through the dynamical analysis. The interactions of $Y_μ$ may provide an explanation for the Bullet Cluster observations. Besides, a possible mechanism to produce $Y_μ$ is discussed.
