论文摘要
我们认为，Sneutrinos可以嵌入多场通货膨胀框架中，在该框架中，两个流域和一个曲线量同时导致原始波动，这与当前的频谱指数的限制是一致的，并通过张贴与量表的比例从Planck和Bicep/Keck 2018中循环说明。最轻的sneutrino的衰变实现了瘦素发生。我们研究了场景的参数范围，例如Sneutrino块的参数。特别是，我们表明，对于成功的方案，张量表与尺度的比率应大于$ 10^{ - 4} $。
We argue that sneutrinos can be embedded in a multi-field inflation framework where two inflatons and a curvaton simultaneously contribute to primordial fluctuations, which is consistent with current constraints on the spectral index and the tensor-to-scalar ratio from Planck and BICEP/Keck 2018. We also show that the same framework can also explain the baryon asymmetry of the Universe via leptogenesis realized by the decay of the lightest sneutrino. We investigate the parameter range for the scenario to work such as that of sneutrino masses. In particular, we show that the tensor-to-scalar ratio should be larger than $10^{-4}$ for a successful scenario.
