Muon, neutrinos, nuSTORM and MICE

I will review the experiments being planned to take the study of neutrino oscillations forward and summarise the programme of measurement required to control systematic uncertainties.

The study of the neutrino is the study of physics beyond the Standard Model. We know that neutrinos have mass and that neutrino flavour oscillates as neutrinos propagate through space and time. Some measurements can be interpreted as hints for new particles known as sterile neutrinos. It is conceivable that the matter-antimatter (CP) symmetry may be violated by neutrino oscillations. To make this profound discovery will require measurements of exquisite precision. Accelerator-based neutrino sources are central to the future programme and advances in accelerator technique are essential.

I will review the experiments being planned to take the study of neutrino oscillations forward and summarise the programme of measurement required to control systematic uncertainties. The potential of muon beams of low emittance to provide the basis for the intense, well-characterised neutrino beams necessary to elucidate the physics of flavour will then be described. Muon beams also have the potential to deliver lepton-anti-lepton collisions at energies of up to several TeV. I will discuss the R&D programme that is required and the contribution that will be made by the International Muon Ionization Cooling Experiment (MICE) and describe the important
