Montero, J. C.Pires, CADPleitez, V2014-05-202014-05-202002-05-01Physical Review D. College Pk: American Physical Soc, v. 65, n. 9, 5 p., 2002.0556-2821http://hdl.handle.net/11449/23905In this work we show that in a version of the 3-3-1 model proposed by Duong and Ma, in which the introduction of a scalar sextet is avoided by adding a singlet heavy charged lepton, the tau lepton gains mass through a seesawlike mechanism. We also show how to generate neutrino masses at the one-loop level, and give the respective Maki-Nakagawa-Sakata mixing matrices for a set of the parameters. We also consider the effect of adding a singlet right-handed neutrino.5engArtigo10.1103/PhysRevD.65.093017WOS:000175914500036Acesso abertoWOS000175914500036.pdf67834333902357270000-0001-5279-8438
