Strangeness and charmness content of nucleon from overlap fermions on 2+1-flavor domain-wall fermion configurations

M. Gong, A. Alexandru, Y. Chen +8

We present a calculation of the strangeness and charmness contents <N|\bar{s}s|N> and <N|\bar{c}c|N> of the nucleon from dynamical lattice QCD with 2+1 flavors. The calculation is…
