Abstract: DC.00005 : Recent progress on Lattice QCD calculation of Nuclear Forces*
10:15 AM–10:30 AM
One of the most fundamental question in nuclear physics is how nuclear physics itself emerges from the underlying theory, quantum chromodynamics (QCD), and the determination of nuclear forces from QCD serves as the cornerstone to answer this question. While nuclear forces have been determined with good precision with phenomenological models and/or effective field theories, many parameters thereof are determined from experimental inputs and the connection to QCD is yet to revealed.
In this talk, we present the first-principles Lattice QCD study for nuclear forces. We introduce the (time-dependent) HAL QCD method, where the interactions are extracted from Nambu-Bethe-Salpeter (NBS) correlators. The importance of this method to perform a reliable calculation on a lattice is discussed. The computation for two- and three-nucleon forces are performed with (unphysically) large quark masses and their implication on nuclear structures are studied. We also perform the first (almost) physical point calculation ($m_\pi$=146 MeV) for two-nucleon forces (as well as hyperon forces) on a large lattice box ($L^4$=(8fm)$^4$). We present these latest results and discuss the future challenges.
