Description

In this presentation, we explore the low-energy behavior of $D{D}^{\ast }$ scattering phase shifts using twisted boundary conditions. While Lüscher’s method is typically employed to calculate scattering phase shifts between two hadrons from energy spectra, it becomes impractical to achieve high-resolution results using only periodic boundary conditions due to volume limitations. Conversely, twisted boundary conditions allow for a more detailed calculation of scattering phase shifts. Our research applies this technique to the $D{D}^{\ast }$ system to gain a deeper understanding of its properties.
