论文摘要
我们研究了具有真实单重标量的Scotogenic模型的扩展。它赋予了大量右撇子中微子的质量，并通过与RICCI标量的非最小耦合发挥了Aftraton的作用。虽然惰性双线标量是该模型中中微子质量产生的必不可少的成分，但它也是一个有希望的暗物质（DM）候选者。如果单重标量表的质量位于共振区域，则引入单线标量可能会影响其DM的性质。我们将研究重点放在这样的情况下，预计充气质量将在TEV范围内，并且加热温度小于$ 10^9 $ GEV。因此，该模型需要低尺度的瘦素发生。在检查了DM扇形的Singlet标量带来的几种影响之后，我们讨论了DM现象学，例如高能量中微子和由其歼灭引起的单色伽马座。
We study an extension of the scotogenic model with a real singlet scalar. It gives an origin of the mass of right-handed neutrinos and plays a role of inflaton through a non-minimal coupling with Ricci scalar. While an inert doublet scalar is an indispensable ingredient for neutrino mass generation in the model, it is also a promising dark matter (DM) candidate. Introduction of the singlet scalar could affect its nature of DM if mass of the singlet scalar is in a resonance region. We focus our study on such a case where inflaton mass is expected to be in a TeV range and reheating temperature is less than $10^9$ GeV. Thus the model requires low scale leptogenesis. After examining several effects brought about by the singlet scalar for the DM sector, we discuss DM phenomenology such as high energy neutrinos and monochromatic gammas caused by its annihilation.
