The Masses of Gauge Bosons in SU(3)_C× SU(2)_L× U(1)_Y^'× U(1)_B-L Gauge Model

We will present within the context of the supersymmetric models with SU(3)_C× SU(2)_L× U(1)_Y^'× U(1)_B-L gauge symmetry an explanation for the new data on the W-boson mass recently presented by the CDF collaboration. We will also study the neutral boson sector of this model.
