CARCAMO HERNANDEZ, A.E.  and  RAHMAN, Rakibur. A SUSY SU(6) GUT model with pseudo-Goldstone Higgs doublets. Rev. mex. fis. [online]. 2016, vol.62, n.2, pp.100-112. ISSN 0035-001X.

We present a novel way of realizing the pseudo-Nambu-Goldstone boson mechanism at all orders in perturbation theory, for the doublet-triplet splitting in supersymmetric grand unified theories. The global symmetries of the Higgs sector are attributed to a non-vectorlike Higgs content, which is consistent with unbroken supersymmetry in a scenario with flat extra dimensions and branes. We also show how in such a model one can naturally obtain a realistic pattern for the Standard Model fermion masses and mixings.

Keywords : Grand unification theories; supersymmetry; fermion masses and mixings.
