چکیده
Two of recent progress in lattice QCD approach to nuclear force are reported. (i) Tensor force from quenched lattice QCD: By truncating the derivative expansion of inter-nucleon potential to the strictly local terms, we obtain central force VC r and tensor force VT r separately from swave and d-wave components of Bethe-Salpeter wave function for two nucleon state with JP 1 . Numerical calculation is performed with quenched QCD on 324 lattice using the standard plaquette action at β 5 7 with the standard Wilson quark action with κ

Lambda-nucleon force from lattice QCD
We study the Λ-nucleon (ΛN) force by using lattice QCD. The Bethe-Salpeter amplitude is calculated for the lowest scattering state of the ΛN so as to obtain the ΛN potential. The numerical calculation is twofold: (i) Full lattice QCD by using 2 + 1 flavor PACS-CS gauge configurations with, β = 1.9, corresponding to the lattice spacing of a = 0.0907(13) fm, on a 323 × 64 lattice. A set of parame...

We report on a direct lattice calculation of the neutron EDM(NEDM) using the external electric field method in both quenched and full QCD. In quenched QCD, we use a 243 × 32 lattice at β = 2.6 with the Iwasaki gauge action and the clover fermion action to examine the viability of this method. In particular we investigate possible effects of violation of the periodic boundary condition of the ex...
متن کاملThe domain wall fermion chiral condensate in quenched QCD
It is a common assertion that quenched lattice QCD qualitatively produces many of the features found in continuum full QCD. However, a quenched simulation is expected to include topological gauge configurations which produce exact fermion zero modes. Not suppressed by the missing fermion determinant, such modes will cause divergent behavior in the small mass limit of the chiral condensate. Surp...
متن کاملNuclear force in Lattice QCD
We perform the quenched lattice QCD analysis on the nuclear force (baryon-baryon interactions). We employ 203 ×24 lattice at β = 5.7 (a ≃ 0.19 fm) with the standard gauge action and the Wilson quark action with the hopping parameters κ = 0.1600,0.1625,0.1650, and generate about 200 gauge configurations. We measure the temporal correlators of the two-baryon system which consists of heavy-light-l...
متن کاملQuenched chiral logarithms in lattice QCD with exact chiral symmetry
We examine quenched chiral logarithms in lattice QCD with overlap Dirac quark. For 100 gauge configurations generated with the Wilson gauge action at β = 5.8 on the 83 × 24 lattice, we compute quenched quark propagators for 12 bare quark masses. The pion decay constant is extracted from the pion propagator, and from which the lattice spacing is determined to be 0.147 fm. The presence of quenche...
