Description

In the two body system, the S matrix in the infinite volume is defined in the rest system, while to obtain more spectra in finite volume, people extract the energy spectrum of finite volume in the moving system. As a result, it needs momentum transformation to connect the energy spectrum in the moving finite volume and the S matrix in the infinite volume. In this work, we find a general formalism of such momentum transformation. In this formalism it has two changeable parameters, then we develop three different transformation equations. The two of them are used in the previous work, and the third one is a new form which will be helpful to develop the Hamiltonian approach in the moving two body system.
