Abstract

We develop an approach based on the Lüshcer's finite size method under twisted boundary conditions. It allows us to evaluate the scattering phase shifts at any small value of the scattering momentum even in a single finite volume. In this study, as a simple example, we demonstrate our method for calculating both S-wave and P-wave J/ψ-scattering phase shifts to search for Y(4140) resonance using 2+1 flavor PACS-CS gauge configuration with partially twisted boundary conditions.
