Lattice QCD studies on baryon interactions in the strangeness -2 sector with physical quark masses


  • Dr. Kenji SASAKI

Primary authors


We investigate baryon-baryon (BB) interactions via the time-dependent HAL QCD method which enables us to derive potentials from Nambu-Bethe-Salpeter (NBS) wave function simulated on the lattice. The simulations are performed with (almost) physical quark masses ($m_\pi=146$ MeV) and a huge lattice volume of La = $8.1$fm. We report the latest results of BB potentials and their scattering observables in the strangeness S=-2 sector. We also discuss the fate of H-dibaryon state through the $\Lambda-\Lambda$ and $N-\Xi$ coupled-channel scatterings.
