Strange quark content of the nucleon hN|¯ss|Ni is calculated in dynamical lattice QCD employing the overlap fermion formulation. For this quantity, exact chiral symmetry guaranteed by the Ginspar...

We report the status of nucleon structure calculations on the (2+1)-flavor dynamical domainwall
fermions ensembles with pion masses as low as 180 and 250 MeV on a lattice with about 4.6 fm spatial ex...

2011/1/13
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 mome...
