论文摘要
我们讨论了标准模型（SM）的最小扩展，其中单个真实标量场既充气和暗物质。相应的Lagrangian包含通气场的可重新分解相互作用。量子效应通常诱导非最小耦合到重力，从而有助于与普朗克约束一致的通货膨胀。通货膨胀后产生的大部分充气量子必须转换为SM辐射，以加热宇宙，其余的仍然是深色物质。我们考虑了充气暗物质的热和非热产生。在非热案件中，我们在晶格模拟的帮助下考虑了集体效应。将分析和数值结果与单位性考虑相结合，我们发现，仅在充气质量接近Higgs质量的一半的热案例中，Adraton暗物质模型才可行。
We discuss a minimal extension of the Standard Model (SM) where a single real scalar field serves as both inflaton and dark matter. The corresponding Lagrangian contains the renormalizable interactions of the inflaton field. Quantum effects generally induce a non-minimal coupling to gravity which facilitates inflation consistent with the PLANCK constraints. A large fraction of the inflaton quanta produced after inflation must be converted into the SM radiation reheating the Universe and the rest remains dark matter today. We consider thermal and non-thermal production of inflaton dark matter. In the non-thermal case, we take into account collective effects with the help of lattice simulations. Combining analytic and numerical results with the unitarity consideration, we find that the inflaton dark matter model is viable only in the thermal case where the inflaton mass is near half the Higgs mass.
