Title: NEUTRINO MIXING WITH NEW HEAVY PARTICLES IN THE <font>SU</font>(6)<sub>L</sub> ⊗ <font>U</font>(1)<sub>Y</sub> MODEL
Abstract: We analyze the effects arisen from the mixing of heavy neutral fermions with the standard neutrinos in the SU (6) L ⊗ U (1) Y model. We obtain limits on the mixing angles between ν e , ν μ , ν τ and the heavy neutral fermions of the model; these results are consistents with those predicted by using certain experimental constraints. This model also gives values for [Formula: see text], for the first row of the CKM matrix and for the invisible decay rate of the Z boson; its close agreement with the experimental data is shown. This behavior is expected since the standard neutrinos only mix with the exotic neutral leptons of the model which acquire mass in the first stage of SSB.
