Description

We present a high-statistics study of nucleon-nucleon scattering in the SU(3) flavor-symmetric limit of QCD, where the light and strange quark masses are tuned to a common value corresponding to $m_\pi \approx 714$. We perform an extraction of NN scattering phase shifts across multiple partial waves using the Lüscher finite-volume quantization condition with multiple boost frames. The high-statistics finite-volume spectra allow us to constrain the effective range expansion parameters and characterize the energy dependence of the scattering amplitudes. We discuss the implications of these results for the structure of baryon-baryon interactions in the SU(3) limit.
