002886973 520__ $$9Springer$$aNeutrino physics is advancing into a precision era with the construction of new experiments, particularly in the few GeV energy range. Within this energy range, neutrinos exhibit diverse interactions with nucleons and nuclei. This study delves in particular into neutrino-nucleus quasi-elastic cross sections, taking into account both standard and, for the first time, non-standard interactions, all within the framework of effective field theory (EFT). The main uncertainties in these cross sections stem from uncertainties in the nucleon-level form factors, and from the approximations necessary to solve the nuclear many-body problem. We explore how these uncertainties influence the potential of neutrino experiments to probe new physics introduced by left-handed, right-handed, scalar, pseudoscalar, and tensor interactions. For some of these interactions the cross section is enhanced, making long-baseline experiments an excellent place to search for them. Our results, including tabulated cross sections for all interaction types and all neutrino flavors, can serve as the foundation for such searches.

Results for $\nu_e$ scattering are very similar. The different colored curves correspond to operators with different Lorentz structures, with the SM ($LL$) case shown in gray. For interactions depending on the axial form factor, we compare different parameterizations of that form factor: the dipole from \cref{eq:axialDip} (dotted), the $z$-expansion fitted to neutrino--deuteron scattering data (dashed), and the $z$-expansion fitted to lattice QCD results (solid). For comparisons, we also show results for neutrino scattering on free nucleons (thinner dot-dashed lines). The content of this plot is available in tabulated form from the Our main cross-section results in tabulated form are available from \href{https://github.com/ztabrizi/EFT-in-Neutrino-Nucleus-Scattering/}{GitHub} \cite{github}.

For the form factors affected by the uncertainty in $G_A(Q^2)$, the left panel shows results for three different parametrizations, namely the dipole form factor with $m_A = \SI{0.961}{GeV}$ (thin solid lines), the $z$-expansion fitted to neutrino--deuterium scattering data (``D2'', shaded bands)~\cite{Meyer:2016oeg}, and a $z$-expansion fit to lattice QCD calculations by the RQCD Collaboration (hatched bands) \cite{RQCD:2019jai}. In the latter two cases, the width of the colored bands indicates the uncertainties quoted in the respective references. The remaining form factors are shown in the right panel. Note the sign change from negative to positive for $G_T^{(1)}$ and from positive to negative for $G_T^{(2)}$.
