Precision Measurements with High Energy Neutrino Beams
Abstract
Neutrino scattering measurements offer a unique tool to probe the electroweak and strong interactions as described by the Standard Model (SM). Electroweak measurements are accessible through the comparison of neutrino neutral- and charged-current scattering. These measurements are complimentary to other electroweak measurements due to differences in the radiative corrections both within and outside the SM. Neutrino scattering measurements also provide a precise method for measuring the F2(x,Q2) and xF3(x,Q2 structure functions. The predicted Q2 evolution can be used to test perturbative Quantum Chromodynamics as well as to measure the strong coupling constant, alpha s, and the valence, sea, and gluon parton distributions. In addition, neutrino charm production, which can be determined from the observed dimuon events, allows the strange-quark sea to be investigated along with measurements of the CKM matrix element |Vcd| and the charm quark mass.
