abstract
We present results on the isoscalar form factors including the disconnected contributions, as well as on the strange and charm quark form factors. Using previous results on the isovector form factors, we determine the flavor decomposition of the nucleon axial form factors. These are computed using an ensemble of $N_f=2+1+1$ twisted mass fermions simulated with physical values of quark masses. We investigate the SU(3) flavor symmetry and show that there is up to 10\% breaking for the axial and up to 50\% for the induced pseudoscalar form factors. By fitting the $Q^2$-dependence, we determined the corresponding root mean square radii. The pseudoscalar coupling of the $\eta$ meson and the nucleon is found to be $g_{\eta NN}=3.7(1.0)(0.7)$, and the Goldberger-Treiman discrepancy for the octet combination about 50\%.

Moving a Detector to Probe New Neutrino Interactions: IWCD at Hyper-Kamiokande
Using the movable IWCD near detector at Hyper-Kamiokande, the NCQE-to-CCQE event ratio sampled at three off-axis angles can constrain axial and vector neutrino non-standard interactions at the 0.05 to 0.12 level, brea...

Radiative corrections in neutral-current (anti)neutrino elastic scattering at $\text{GeV}$ energies I: Nucleon targets
Radiative corrections to neutral-current (anti)neutrino-nucleon elastic scattering are computed within low-energy EFT and reach a few percent, comparable to the strange-quark effects they must be disentangled from.

Neutrino nucleus Quasi-Elastic and resonant Neutral Current scatterings with Non-Standard Interactions
Axial non-standard neutrino interactions can mimic or be disentangled from nucleon form-factor effects in neutral-current quasi-elastic and resonance scattering, and tau-flavor couplings may already be bounded by KamL...

Nucleon relativistic weak-neutral axial-vector four-current distributions
The 3D axial charge density of a spin-1/2 hadron is parity-odd and controlled by the induced pseudotensor form factor G_T^Z, while the second-class current drops out of the mean-square axial and spin radii.

Polarization Probes of New Physics in Lepton-Flavor-Violating Hyperon Production from $e^- N \to \tau^- Y$ Scattering
Polarization asymmetries in e-N to tau-Y scattering could distinguish hyperon form factor models and the chiral nature of new lepton-flavor-violating vector interactions, but predicted rates are at most a few hundred ...
