    Weak neutral current axial form factor using ν ¯ ν $$ \left(\overline{\nu}\right)\nu $$ -nucleon scattering and lattice QCD inputs by Raza Sabbir Sufian, Keh-Fei Liu, David G. Richards

    Published 2020-01-01
    “…We show a consistent description of G A Z Q 2 $$ {G}_A^Z\left({Q}^2\right) $$ obtained from the (anti)neutrino-nucleon scattering cross section data requires a nonzero contribution of the strange quark electromagnetic form factor. We demonstrate the robustness of our analysis by providing a post-diction of the BNL E734 experimental data.…”
