我们提出了一个变体方案的自发重子从非对称暴胀的基础上与非零B− L电荷的物质场之间的电流-电流的相互作用。当暴胀子在暴胀后开始在最小值附近振荡时，它可能导致CP奇分量的激发，这通过电流-电流相互作用诱导出B− L数的有效化学势。我们研究了具体的暴胀模型，并证明了自发重子生成方案可以在超引力下的混沌暴胀中自然实现。
We propose a variant scenario of spontaneous baryogenesis from asymmetric inflaton based on current–current interactions between the inflaton and matter fields with a non-zero B− L charge. When the inflaton starts to oscillate around the minimum after inflation, it may lead to excitation of a CP-odd component, which induces an effective chemical potential for the B− L number through the current–current interactions. We study concrete inflation models and show that the spontaneous baryogenesis scenario can be naturally implemented in the chaotic inflation in supergravity.
