Pires, CADda Silva, PSR2014-05-202014-05-202002-04-01Physical Review D. College Pk: American Physical Soc, v. 65, n. 7, 7 p., 2002.0556-2821http://hdl.handle.net/11449/23376We investigate some proposals to solve the electric charge quantization puzzle that simultaneously explain the recent measured deviation on the muon anomalous magnetic moment. For this we assess extensions of the electro-weak standard model spanning modifications on the scalar sector only. It is interesting to verify that one can have modest extensions which easily account for the solution for both problems.7engArtigo10.1103/PhysRevD.65.076011WOS:000174980200057Acesso abertoWOS000174980200057.pdf
