The Terrestrial Neutrino Lighthouse
Adrian Thompson (Northwestern University)
Wednesday, June 4, 15:00 UTC (10:00 am Central US)
Abstract:
We investigate the sensitivity of a companion neutrino detector situated in the plane of a high-energy, high-intensity muon storage ring to elastic neutrino scattering on electrons (EνES). Assuming a muon collider with center-of-mass energies of up to 10 TeV, we report sensitivity to the weak couplings up to around 0.05% relative error, and sensitivity to the weak mixing angle in the 0.01 - 2 GeV momentum transfer GeV range up to around 0.03% relative error. EνES measurements with high-energy muon storage rings allow one to interrogate the momentum-transfer regime associated with the NuTeV anomaly. This level of precision allows unique sensitivity to the momentum-dependence of the weak mixing angle. We estimate that with the neutrinos from a TeV-scale muon collider, the hypothesis that the weak mixing angle does not “run” can be safely ruled out. Lastly, we motivate several future directions and channels to study to better measure electroweak physics and search for new physics beyond the Standard Model.
