Nucleon strange quark content from two-flavor lattice QCD with exact chiral symmetry
Nucleon strange quark content two-flavor lattice QCD
2010/11/30
Strange quark content of the nucleon is calculated in dynamical lattice QCD employing the overlap fermion formulation. For this quantity, exact chiral symmetry guaranteed by the Ginsparg-Wilson relati...

Systematic errors extracting nucleon properties
2010/11/30
Form factors of the nucleon have been extracted from experiment with high precision. However, lattice calculations have failed so far to reproduce the observed dependence of form factors on the moment...

Charmonium-nucleon interaction from lattice QCD with a relativistic heavy quark action
Charmonium-nucleon lattice QCD relativistic heavy quark action
2010/11/30
Detailed information of the low-energy interaction between the charmonia ({\eta}c and J/{\psi}) and the nucleon is indispensable for exploring the formation of charmonium bound to nuclei. In order to ...

The study of the Three Nucleon Force in full QCD Lattice calculations
the Three Nucleon Force full QCD Lattice calculations
2010/11/30
We study the three nucleon force in the triton channel using dynamical clover fermion lattice QCD. The Nambu-Bethe-Salpeter wave function is utilized to obtain the potentials among three nucleons. Sin...
Study of nucleon resonances in a chiral quark model via η productions
N* chiral quark model photoproduction
2009/11/24
In this report we investigate η-meson productions on the proton via electromagnetic and hadron probes in a chiral quark model approach. The observables, such as, differential cross section and beam a...
Scaling property in one-nucleon removal reactions induced by exotic nuclei
fragment momentum distribution few-body Glauber model
2009/8/14
Assuming a core plus valence nucleon structure, one-nucleon removal reaction
is investigated within the framework of few-body Glauber theory. Fermi-type distribution is used for the core density, wh...
Nucleon Magnetic Moments in Light-Front Models with Quark Mass Asymmetries
Nucleon Magnetic Moments Light-Front Models Quark Mass Asymmetries
2004/9/30
We show that the systematic inconsistence found in the simultaneous fit of the neutron and proton magnetics moments in light-front models, disappears when one allows an asymmetry in the constituent qu...
