Type II Seesaw and a Gauge Model for the Bimaximal Mixing Explanation of Neutrino Puzzles
R. N. Mohapatra, A. Pérez-Lorenzana, C. A. de S. Pires
We present a gauge model for the bimaximal mixing pattern among the neutrinos that explains both the atmospheric and solar neutrino data via large angle vacuum oscillation among th…
Spontaneous breaking of a global symmetry in a 331 model
J. C. Montero, C. A. de S. Pires, V. Pleitez
In a 331 model in which the lepton masses arise from a scalar sextet it is possible to break spontaneously a global symmetry implying in a pseudoscalar majoron-like Goldstone boson…
Comment on ``Majoron emitting neutrinoless double beta decay in the electroweak chiral gauge extensions''
J. C. Montero, C. A. de S. Pires, V. Pleitez
We point out that if the majoron-like scheme is implemented within a 331 model, there must exist at least three different mass scales for the scalar vacuum expectation values in th…
Remark on the vectorlike nature of the electromagnetism and the electric charge quantization
C. A de S. Pires
In this work we study the structure of the electromagnetic interactions and the electric charge quantization in gauge theories of electroweak interactions based on semi-simple grou…
