论文摘要
考虑了$ 1+1 $ dimensional $ ϕ^4 $模型的扭结/反键散射的集体坐标近似，我们讨论了如何通过在参数空间中为Lagrangian提供分析表达来改善该主题的结果。为完整性提供了对集体协调近似值的作用的全面讨论。
The collective coordinates approximation for the kink/anti-kink scattering in the $1+1$ dimensional $ϕ^4$ model is considered and we discuss how the results found in the current literature on the topic can be improved by giving the analytical expression for the lagrangian in the space of parameters. A comprehensive discussion of the role of the collective coordinates approximation in this particular situation is given for completeness.
