Query: Nucleon mass and strange content from (2+1)-flavor Domain Wall Fermion   We report on our ongoing study of nucleon properties, the nucleon mass and
the strange quark content (<N|ss|N>) in particular. These calculations are done
on (2+1)-flavor Domain Wall Fermion (DWF) ensembles with Iwasaki gauge action
with 2 different lattice spacings (a ~ 0.08, 0.11fm) and DWF with Dislocation
Suppressing Determinant Ratio(DSDR) (a ~ 0.14fm), generated by RBC/UKQCD
collaborations.
