Using a 3 + 1 neutrino model with one sterile and the three standard active
neutrinos with a 4x4 unitary transformation matrix, U, relating flavor to mass
neutrino states, the probability of νμ​ to νe​ transition is
estimated using sterile-active neutrino masses determined by MiniBooNE and
other experiments and sterile-active neutrino angles in the 4x4 U matrix.Comment: 8 pages, 3 figure
