我们提出了一种产生宇宙重子()不对称性的最小方法，其中不对称性是通过破坏二次膨胀子势项和Affleck-Dine机制在复杂的膨胀凝聚体中产生的。我们发现，在后期，违反二次质量项的复数膨胀凝聚体产生了振荡的不对称性。在再加热时转移到标准模型扇区的最终不对称性，由于振荡的平均化效应，自然减少到观察到的不对称性的大小。这种重子发生的方法可以很容易地在各种膨胀模型中实现。
We present a minimal approach to the generation of the baryon () asymmetry of the Universe, in which the asymmetry is generated in a complex inflaton condensate via-violating quadratic inflaton potential terms and the Affleck-Dine mechanism. We show that the-violating quadratic mass terms create an oscillating asymmetry in the complex inflaton condensate at late times. The final asymmetry transferred to the Standard Model sector at reheating is naturally reduced to the magnitude of the observedasymmetry by the effect of averaging over theoscillations. This approach to baryogenesis can easily be realized in a wide range of inflation models.
