The first results of lattice QCD simulations on the nucleon tensor charge $\ensuremath{\delta}q$ are presented. From the quenched QCD simulations with the Wilson quark action at $\ensuremath{\beta}=5.7$ (the lattice spacing $a\ensuremath{\simeq}0.14$ fm) on a 16${}^{3}\ifmmode\times\else\texttimes\fi{}$20 lattice and on a ${12}^{3}\ifmmode\times\else\texttimes\fi{}20$ lattice, we find (i) the connected part $\ensuremath{\delta}{q}_{\mathrm{con}}$ is determined with small statistical error, (ii…

Instanton induced transverse single spin asymmetry for π0 production in pp scattering

We calculate the production cross section and the transverse single-spin asymmetry for pion in ${p}^{\ensuremath{\uparrow}}+p\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}+X$. Our computation is

Chiral symmetry and the nucleon spin structure functions

We carry out a systematic investigation of twist-two spin dependent structure functions of the nucleon within the framework of the chiral quark soliton model (CQSM) by paying special attention to the

The Electric Dipole Moment of $^{13}$C

We calculate for the first time the electric dipole moment (EDM) of $^{13}$C generated by the isovector CP-odd pion exchange nuclear force in the $\alpha$-cluster model, which describes well the

Examination of the strangeness contribution to the nucleon magnetic moment

We examine the nucleon strangeness magnetic moment {mu}{sub s} with a lowest order meson cloud model. We observe that (1) strangeness in the nucleon is a natural requirement of the empirical relation

QCD sum rules for hyperon-nucleon interactions

We investigate the hyperon-nucleon interactions in the QCD sum rule starting from the nucleon matrix element of the hyperon correlation function. Through the dispersion relation, the correlation

Spin orbital structure of the nucleon magnetic moment

How the nucleon magnetic moment originates from the quark spin and orbital motions is an important issue of the nucleon structure. The Gordon decomposition separates the quark vector current and

Aspects of hadron and instatnton physics in lattice quantum field theories

An ongoing challenge to quantum chromodynamics as the theory of strong interactions is calculating hadron masses and matrix elements from first principles. Presently lattice calculations are the most

Single-spin asymmetry in electro-production of $\pi^+\pi^-$ pairs from a transversely polarized proton target at the HERMES experiment

Spin structure of the nucleon is one of the fundamental topics in physics. The proton has spin 1/2, and contains quarks with spin 1/2 and gluons with spin 1. Three fundamental quark distribution
