Unified supersymmetric model of naturally small Dirac neutrino masses and the axionic solution of the strong CP problem

摘要

Using the particle content of the fundamental 27 supermultiplet of E-6, naturally small Dirac neutrino masses are obtained in the context of SU(3)(C) x SU(2)(L) x U(1)gamma x U(1)(chi), where U(1)(chi) comes from the decomposition E-6 --> SO(10) x U(1)(psi), then SO(10) --> SU(5) x U(1)(chi). New observable consequences are predicted at the TeV scale. An axionic solution of the strong CP problem may be included at no extra cost. (C) 2002 Elsevier Science B.V. All rights reserved.
