On the generation of the particles through spontaneous symmetry breaking

In this paper we present the Weiberg-Salam-Glashow model of the electroweak interactions. With a specific choice of parameters can be obtained massive Z and W$^{\pm}$ bosons , while keeping the photon massless. These results are obtained by breaking the local gauge invariant SU(2)$_L \times$ U(1)$_Y$ symmetry. The same Higgs doublet which generates W$^{\pm}$ and Z masses is also sufficient to give masses to the leptons.
