论文摘要
提出了明显的相对论不变的Lellouch-lüscher形式主义,以实施三粒子衰变。类似地,与参考文献[1]一样,形式主义是基于使用非忠实的有效拉格朗日人的使用。如参考文献[2]中,可以保证明显的洛伦兹不变性,通过选择沿三粒子系统的总四孔选择量化轴。解决了高阶导数耦合以及更高的部分波的系统包含。
A manifestly relativistic-invariant Lellouch-Lüscher formalism for the three-particle decays is proposed. Similarly to ref.[1], the formalism is based on the use of the non-relativistic effective Lagrangians. Manifest Lorentz invariance is guaranteed, as in ref.[2], by choosing the quantization axis along the total four-momentum of the three-particle system. A systematic inclusion of the higher-order derivative couplings, as well as higher partial waves is addressed.
