Determining the Flavour Content of the Low-Energy Solar Neutrino Flux


We study the sensitivity of the HELLAZ and Borexino solar neutrino experiments on discriminating the neutrino species νe, ν̄e, νμ,τ , ν̄μ,τ , and νs using the difference in the recoil electron kinetic energy spectra in elastic neutrino-electron scattering. We find that one can observe a non-vanishing νμ,τ component in the solar neutrino flux, especially… (More)
