abstract

The planned DUNE experiment will have excellent sensitivity to the vector and axial couplings of the electron to the $Z$-boson via precision measurements of neutrino--electron scattering. We investigate the sensitivity of DUNE-PRISM, a movable near detector in the direction perpendicular to the beam line, and find that it will qualitatively impact our ability to constrain the weak couplings of the electron. We translate these neutrino--electron scattering measurements into a determination of the weak mixing angle at low scales and estimate that, with seven years of data taking, the DUNE near-detector can be used to measure $\sin^2\theta_W$ with about 2\% precision. We also discuss the impact of combining neutrino--electron scattering data with neutrino trident production at DUNE-PRISM.

  1. The Neutrino Slice at Muon Colliders

    hep-ph 2024-12 conditional novelty 7.0 of 10

    Beam-induced neutrinos at a muon collider would yield around 10^11 interactions per year in the main detector, enabling precision electroweak and neutrino measurements.

  2. Neutrino Induced Charged Current Coherent Pion Production for Constraining the Muon Neutrino Flux at DUNE

    hep-ph 2025-02 conditional novelty 6.0 of 10

    Monte Carlo projections indicate that neutrino-induced coherent pion production can constrain the DUNE muon-neutrino flux normalization to about 1.5% (in-situ pion-argon measurement) or 2-5% (external pion-argon data)...

  3. Diffuse Supernova Neutrino Background and Neutrino Non-Radiative Decay: a Bayesian Perspective

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A Bayesian forecast of upcoming DSNB detectors shows neutrino decay can be distinguished from stability for quasi-degenerate or inverted mass patterns, but not for strong normal hierarchy.

  4. Probing Light Dark Particles in Neutrino Scattering Experiments

    hep-ph 2026-02 conditional novelty 5.0 of 10

    A dark fermion produced in neutrino scattering could be probed at DUNE's near detector up to cutoff scales near 1 TeV, beyond CHARM II and LEP, while current COHERENT/CONUS+ limits stay below LHC bounds.
