The Masses of Gauge Bosons in $SU(3{)}_C\times SU(2{)}_L\times U(1{)}_{Y^{\mathrm{\prime }}}\times U(1{)}_{B-L}$ gauge model

We will present within the context of the supersymmetric models with $SU(3{)}_C\times SU(2{)}_L\times U(1{)}_{Y^{\mathrm{\prime }}}\times U(1{)}_{B-L}$ 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.
