Description

The standard candles of electroweak observables can be studied through the lens of neutrino-electron scattering as a purely weak process. We project the sensitivity of a neutrino detector situated around 100 meters away in the plane of a high energy muon storage ring or muon collider with $E_\mu = 0.25, 1.5$, and $5$ TeV muon beam energies, providing a highly energetic and highly intense source of electron and muon (anti)neutrinos. We find world-leading sensitivity to the weak couplings at the sub-percent level is possible, with sensitivity to the Standard Model prediction for the neutrino charge radius. Finally, we show that sensitivity to the momentum transfer dependence of $\sin^2\theta_W$ at the $0.01\%$ level, within a single dataset and configuration of the proposed experiment, is possible.
