Universal Doublet-Singlet Higgs Couplings and phenomenology at the CERN Large Hadron Collider
Gautam Bhattacharyya, Gustavo C. Branco, S. Nandi
We consider a minimal extension of the standard model where a real, gauge singlet scalar field is added to the standard spectrum. Introducing the Ansatz of universality of scalar c…
Four Zero Neutrino Yukawa Textures in the Minimal Seesaw Framework
Gustavo C. Branco, David Emmanuel-Costa, M. N. Rebelo +1
We investigate, within the Type I seesaw framework, the physical implications of zero textures in the Yukawa couplings which generate the neutrino Dirac mass matrix . It is sh…
Neutrino Physics and CP violation
G. C. Branco, M. N. Rebelo
We review some aspects of neutrino physics and CP violation both in the quark and lepton sectors.
Weak Basis Transformations and Texture Zeros in the Leptonic Sector
G. C. Branco, D. Emmanuel-Costa, R. Gonzalez Felipe +1
We investigate the physical meaning of some of the texture zeros which appear in most of the Ansatze on leptonic masses and their mixing. It is shown that starting from arbitrary l…
CP Violation and Flavour Mixings in Orbifold GUTs
Gautam Bhattacharyya, Gustavo C. Branco, Joaquim I. Silva-Marcos
We address the flavour problem by incorporating the hypothesis of universal strength of Yukawa couplings in the framework of a 5D GUT model compactified on an $S^1/(Z_2 \times Z_2^…
