Abstract

A simple unifying mass matrix is presented for the three active and one sterile neutrinos

ν_{e},

ν_{μ},

ν_{τ},

and

ν_{s},

using an extension of the radiative mechanism proposed some time ago by Zee. The total neutrino-oscillation data are explained by the scheme

ν_{e} \leftrightarrow ν_{s}

(solar),

ν_{μ} \leftrightarrow ν_{τ}

(atmospheric) and

ν_{e} \leftrightarrow ν_{μ}

(LSND). We obtain the interesting approximate relationship

(Δ m^{2})_{atm} ≃ 2 [(Δ m^{2})_{solar} (Δ m^{2})_{LSND}]^{1 / 2}

which is well satisfied by the data.
