Naturally light invisible axion in models with large local discrete symmetries

Alex G. Dias, V. Pleitez, M. D. Tonasse

We show that by introducing appropriate local $Z_{N} (N \geq 13)$ symmetries in electroweak models it is possible to implement an automatic Peccei-Quinn symmetry keeping at the same tim…

Naturally light invisible axion and local Z_{13} times Z_3 symmetries

Alex G. Dias, V. Pleitez, M. D. Tonasse

We show that by imposing local $Z_{13} \otimes Z_{3}$ symmetries in an $S U (2) \otimes U (1)$ electroweak model we can implement an invisible axion in such a way that (i) the Peccei-Quin…

Left-right asymmetries, the weak mixing angle, and new physics

J. C. Montero, V. Pleitez, M. C. Rodriguez

The goal of this article is to outline the advantages of the measurement of left-right asymmetries in lepton-lepton ( $l^{-} l^{-} \to l^{-} l^{-}$ ) scattering for performing precision…

Realistic extremely flat scalar potential in 3-3-1 models

Alex G. Dias, V. Pleitez, M. D. Tonasse

We show that in 3-3-1 models it is possible to implement an extremely flat scalar potential, i.e., a zero contribution to the cosmological constant, and still having realistic valu…
