Description
A brief overview of the derivation of the manifestly relativistic-invariant expression for the Lellouch-Lüscher factor in three-particle decays is given. Furthermore, the framework has been explicitly applied to the decay process of a kaon into three (non-identical) pions at leading order. The role of the three-particle force is investigated in detail.
