We present full accounts of a method to extract nucleon-nucleon ( NN ) potentials from the Bethe-Salpter amplitude in lattice QCD. The method is applied to two nucleons on the lattice with quenched QCD simulations. By disentangling the mixing between the Sstate and the D-state, we obtain central and tensor potentials in the leading order of the velocity expansion of the non-local NN potential. The spatial structure and the quark mass dependence of the potentials are analyzed in detail. Subject… 

Lambda-Nucleon and Nucleon–Nucleon Interactions on the Lattice

Lattice QCD study of nuclear potentials is reported. A lattice QCD method to calculate realistic nuclear potentials is developed. In this method, Bethe–Salpeter wave functions generated on the

We derive an energy-independent and non-local potential for the baryon-baryon interaction from the Nambu-Bethe-Salpeter amplitude on the lattice. The method is applied to the nucleon-nucleon

We present the latest lattice QCD results for baryon interactions obtained at nearly physical quark masses. Nf = 2 + 1 nonperturbatively O(a) -improved Wilson quark action with stout smearing and

Nucleon-nucleon interactions via Lattice QCD: Methodology

We review the potential method in lattice QCD, which has recently been proposed to extract nucleon-nucleon interactions via numerical simulations. We focus on the methodology of this approach by

We studied the single-particle potential of Λ, Σ, and Ξ hyperons in nucleonic matter starting from the fundamental theory of the strong interaction, QCD. First, we carried out a lattice QCD numerical

Lattice QCD approach to Nuclear Physics

We review recent progress of the HAL QCD method which was recently proposed to investigate hadron interactions in lattice QCD. The strategy to extract the energy-independent non-local potential in

Bound H-dibaryon from Full QCD Simulation on the Lattice

Using a new method recently proposed by the HAL QCD collaboration to study hadron interactions in lattice QCD, we investigate a possibility for an existence of the H-dibaryon in the flavor SU(3)

Coupled Channel Approach to S-Wave Hyperonic Interactions from Lattice QCD

We studied hyperonic interactions by lattice QCD simulation throuth coupled channel formalism. Our approach to baryon-baryon interactions is deriving a potential from inverting Schrödinger equation



The nuclear force from Monte Carlo simulations of lattice quantum chromodynamics

The nuclear force acting between protons and neutrons is studied in the Monte Carlo simulations of the fundamental theory of strong interaction, the quantum chromodynamics defined on the hypercubic

We report on our recent study of flavor singlet matrix elements calculated with the wall source method without gauge fixing. Results are presented for the mass difference between $\eta^{\prime}$ and

A status report is made of an on-going full QCD study on the CP-PACS aiming at a comparative analysis ofthe effects of improving gauge and quark actions on hadronic quantities and static quark

The XXVIII International Symposium on Lattice Field Theory

We represent thin and dressed Polyakov loops as spectral sum s of eigenvalues of differential operators on the lattice. For that purpose we calculate comple te sets of eigenvalues of the staggered
