abstract = {We report a direct lattice QCD calculation of the strange
nucleon electromagnetic form factors $G_E^s$ and $G_M^s$ in
the kinematic range 0≤Q²≲1.2GeV². For the first time,
both $G_E^s$ and $G_M^s$ are shown to be nonzero with high
significance. This work uses closer-to-physical lattice
parameters than previous calculations, and achieves an
unprecedented statistical precision by implementing a
recently proposed variance reduction technique called
hierarchical probing. We perform model-independent fits of
the form factor shapes using the z-expansion and determine
the strange electric and magnetic radii and magnetic moment.
We compare our results to parity-violating electron-proton
scattering data and to other theoretical studies.},
