Mass matrix for atmospheric, solar, and LSND neutrino oscillations
Mass matrix for atmospheric, solar, and LSND neutrino oscillations
We construct a mass matrix for the four neutrino flavors, three active and one sterile, needed to fit oscillations in all three neutrino experiments: atmospheric, solar, and LSND, simultaneously. It organizes the neutrinos into two doublets whose central values are about $1 \mathrm{eV}$ apart, and whose splittings are of the …
