论文摘要
我们研究了一种通货膨胀模型的宇宙学后果，该模型结合了粒子物理标准模型的通用Seesaw扩展（I型和II）。在一个循环顺序下，充气场和RICCI标量之间的非最小耦合被认为是辐射校正的。通货膨胀动力学与中微子物理学之间的这种联系导致了一个预测模型，该模型根据当前的宇宙微波背景数据，Baryon声学振荡观测和IA型超新星测量，研究了观察力的活力。我们的结果表明，当辐射校正为正时，非最小耦合的SEESAW电势可以很好地描述观察数据。这样的结果比I型II型SeeSAW机制有利于I型机制，并且可能是标准模型以外的物理学的指示。
We investigate cosmological consequences of an inflationary model which incorporates a generic seesaw extension (types I and II) of the Standard Model of Particle Physics. A non-minimal coupling between the inflaton field and the Ricci scalar is considered as well as radiative corrections at one loop order. This connection between the inflationary dynamics with neutrino physics results in a predictive model whose observational viability is investigated in light of the current cosmic microwave background data, baryon acoustic oscillation observations and type Ia supernovae measurements. Our results show that the non-minimal coupled seesaw potential provides a good description of the observational data when radiative corrections are positive. Such result favours the type II seesaw mechanism over type I and may be an indication for physics beyond the Standard Model.
