论文摘要
使用非相关主义有效的场理论,我们在领先顺序下得出了Lellouch-Lüscher公式的三粒子类似物。该公式将有限体积的三粒子衰减幅度与其无限体积的对应物相关联,因此可以用于研究晶格上的三粒子衰变。简要讨论了高级订单方法的概括。
Using non-relativistic effective field theory, we derive a three-particle analog of the Lellouch-Lüscher formula at the leading order. This formula relates the three-particle decay amplitudes in a finite volume with their infinite-volume counterparts and, hence, can be used to study the three-particle decays on the lattice. The generalization of the approach to higher orders is briefly discussed.
