论文摘要
使用多场随机方法，我们研究了在轻度破碎的全局$ u（1）$对称性的标量膨胀期间的真空期望值（VEV），该量子场可以扮演Baryon或Lepton数字的作用，或者可能是黑暗的Baryon数字或三个组合。即使对于CP不变的Lagrangian，通货膨胀VEV的随机分布也会自发地断裂CP，从而通过Affleck-Dine机制成功地进行了Baryogenogeny。对于通货膨胀期间的哈勃尺度$ h_ \ ast $高达$ 10^{13} $ gev，我们表明，具有随机初始条件的带电标量的通货膨胀后放松可以解释观察到的baryon不对称性，并且以$ h_ \ ast $的顺序为$ h_ \ ast $ affecter of the Baryon的不对称质量。
Using a multi-field stochastic approach, we investigate the vacuum expectation value (VEV) during inflation of a scalar field charged under a mildly broken global $U(1)$ symmetry that can play the role of baryon or lepton number, or possibly a dark baryon number or a combination of the three. Even for a CP invariant Lagrangian, the stochastic distribution of inflationary VEVs in general breaks CP spontaneously, allowing for successful baryogenesis via the Affleck-Dine mechanism. For the Hubble scale during inflation $H_\ast$ as high as $10^{13}$ GeV, we show that the post-inflationary relaxation of the charged scalar with stochastic initial conditions can explain the observed baryon asymmetry, and that a charged scalar mass at the order of $H_\ast$ is favored by the isocurvature constraints.
