Weak charges in $SU(5)_{L} \times U(1)_{Y}$ gauge models
Within the framework of a renormalizable $SU(5)_{L} \times U(1)_{Y}$ electro-weak gauge model with no exotic electric charges, we obtain all the neutral weak charge operators and their quantization, once the diagonalization of the neutral boson mass matrix is properly performed. Our results open up the path to a rich and promising phenomenological outcome. All the Standard Model phenomenology is recovered by simply decoupling the latter's scale ($v_{SM}=246$ GeV) from the higher scale ($V\sim$ 10 TeV) specific to our new electro-weak unification.
