Bounds on the Simplest Little Higgs Model Mass Spectrum Through Z Leptonic Decay

Alex G. Dias, C. A. de S. Pires, P. S. Rodrigues da Silva

We derive the leptonic neutral current in the simplest little Higgs model and compute the contribution of the model to the decay width $Z \to e^{+} e^{-}$ . Using the precision electrowe…

An SU(5) $\otimes$ Z_{13} Grand Unification Model

Alex G. Dias, Edison T. Franco, Vicente Pleitez

We propose an SU(5) grand unified model with an invisible axion and the unification of the three coupling constants which is in agreement with the values, at $M_{Z}$ , of $α$ , $α_{s}$ ,…
