The liquid-argon-based detectors planned for DUNE are expected to be uniquely sensitive to the {\&} nu;e component of the supernova flux, enabling a wide variety of physics and astrophysics measurements. A key requirement for a correct interpretation of these measurements is a good understanding of the energy-dependent total cross section {\&} sigma;oE {\&} nu; thorn for charged-current {\&} nu;e absorption on argon. In the context of a simulated extraction of supernova {\&} nu;e spectral parameters from a toy analysis, we investigate the impact of {\&} sigma;oE {\&} nu; thorn modeling uncertainties on DUNE{\textquoteright}s supernova neutrino physics sensitivity for the first time. We find that the currently large theoretical uncertainties on {\&} sigma;oE {\&} nu; thorn must be substantially reduced before the {\&} nu;e flux parameters can be extracted reliably; in the absence of external constraints, a measurement of the integrated neutrino luminosity with less than 10{\%} bias with DUNE requires {\&} sigma;oE {\&} nu; thorn to be known to about 5{\%}. The neutrino spectral shape parameters can be known to better than 10{\%} for a 20{\%} uncertainty on the cross-section scale, although they will be sensitive to uncertainties on the shape of {\&} sigma;oE {\&} nu; thorn . A direct measurement of low-energy {\&} nu;e-argon scattering would be invaluable for improving the theoretical precision to the needed level.", optnote="WOS:001063367400002", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=5669), last updated on Fri, 26 Apr 2024 07:26:44 +0000", issn="2470-0010", doi="10.1103/PhysRevD.107.112012", opturl="https://arxiv.org/abs/2303.17007", opturl="https://doi.org/10.1103/PhysRevD.107.112012", language="English" }
