论文摘要
使用高阶微分方程的确切WKB分析，我们分析了复杂标量场的动态粒子产生中的不对称性。该解决方案需要四阶微分方程的现象。我们发现，不同类型的Stokes现象的干扰会导致物质 - 抗焦点不对称。我们还展示了一个具体的示例，其中确切计算中禁止不对称，但是在扰动膨胀中出现错误的不对称性。
Using the exact WKB analysis of the higher-order differential equations, we analyze the asymmetry in dynamical particle production of a complex scalar field. The solution requires the Stokes phenomena of the fourth-order differential equation. We found that the interference of different types of the Stokes phenomena causes matter-antimatter asymmetry. We also showed a specific example where asymmetry is forbidden in the exact calculation, but a false asymmetry appears in the perturbative expansion.
