Lattice QCD study on the strangeness -2 baryonic states
ORAL
Abstract
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 = 8.1fm.
We report the latest results of BB potentials and their scattering observables in the strangeness S=-2 sector.
We also discuss the possibility of H-dibaryon state through the Lambda-Lambda and N-Xi scatterings.
