Nucleon sigma term and strange quark content in 2+1-flavor QCD with dynamical overlap fermions
arXiv:0910.3271
Abstract
We study the sigma term and the strange quark content of nucleon in 2+1-flavor QCD with dynamical overlap fermions. We analyze the lattice data of nucleon mass taken at two different strange quark masses with five values of up and down quark masses each. Using the reweighting technique, we study the strange quark mass dependence of the nucleon and extract the strange quark content.
