Abstract
We determine the nucleon neutral weak electromagnetic form factors by combining results from light-front holographic QCD and lattice QCD calculations. We deduce nucleon electromagnetic form factors from light-front holographic QCD which provides a good parametrization of the experimental data of the nucleon electromagnetic form factors in the entire momentum transfer range and isolate the strange quark electromagnetic form factors using lattice QCD. From these calculations, we obtain precise estimates of the neutral weak form factors in the momentum transfer range of . From the lattice QCD calculation, we present -dependence of the strange quark form factors. We also deduce the neutral weak Dirac and Pauli form factors of the proton and the neutron.
