Gauge boson masses for a minimal $SU(4)_{EW} \otimes U(1)_{B-l}$model]{Following the general procedure of spontaneous symmetry breaking of a$SU(4)_{EW} \otimes U(1)_{B-l}$ electroweak gauge group with left-rightsymmetry, we obtain the gauge boson masses and currents for the minimal versionof the model. The physical eigenstates for neutral gauge bosons are determinedby introducing two mixing angles $\theta_4$ and $\theta_3$ which are related tothe electroweak mixing angle $\theta_w$ at the unification scale. Byintroducing some physical approaches in order to simplify the calculations, wecalculate the charged and neutral currents. Differently from other previouspropositions, the results are obtained from a theoretical constraint upon thecoupling constants as a consequence of embedding the symmetry into thePati-Salam electroweak coupling $SU(4)_{EW} \otimes SU(4)_{PS}$.Comment: 21 page
