论文摘要
我们提出了一种最少的方法，可以使宇宙的重子（$ b $）的不对称产生，其中使用Affleck-Dine（AD）机制通过$ b $ violation二次发电量通过$ b $ violation二次发电量产生了不对称性。我们表明，$ b $侵略的二次质量术语在较晚的复杂充气冷凝物中产生了振荡的不对称性。通过在$ b $振荡上平均的效果，将最终转移到标准模型部门的最终不对称性自然减少到观察到的$ b $不对称性的大小。这种男生成方法可以很容易地在广泛的通货膨胀模型中实现。我们还表明，通过加速器质量项的AD男性生成不含常规AD机制所需的场动力学调整。
We present a minimal approach to the generation of the baryon ($B$) asymmetry of the Universe, in which the asymmetry is generated in a complex inflaton condensate via $B$-violating quadratic inflaton potential terms using the Affleck-Dine (AD) mechanism. We show that the $B$-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 observed $B$ asymmetry by the effect of averaging over the $B$ oscillations. This approach to baryogenesis can easily be realised in a wide range of inflation models. We also show that AD baryogenesis via inflaton mass terms is free of the tuning of field dynamics required by the conventional AD mechanism.
