| Title | Weak Neutral Current Axial Form Factor Using (v-)v-Nucleon Scattering and Lattice QCD Inputs | ||||
| Abstract | The interplay of first-principles lattice QCD calculations and experimental results can unveil such nucleon properties to higher precision and accuracy than either theory or experiment alone can obtain. In this simple yet novel analysis, using a combination of the strange quark electromagnetic form factors from lattice QCD and (anti)neutrino-nucleon neutral current elastic scattering differential cross section data from MiniBooNE experiments in a kinematic region $0.3\lesssim Q^2 \lesssim 0.7$ GeV$^2$, we obtain, \textit{(1)} the most precise determination of the weak neutral current axial form factor with weak axial charge $G^Z_A(0)=-0.734(63)(20)$, \textit{(2)} strange quark contribution to the proton spin $\Delta s= -0.196(127)(41)$, \textit{(3)} reconstruct the MiniBooNE data along with the prediction of BNL E734 (anti)neutrino-nucleon scattering differential cross section data in the $0 \lesssim Q^2\leq 1$ GeV$^2$ momentum transfer region to test the validity and predictive powe | ||||
