Anomalies, Beta Functions and Supersymmetric Unification with Multi-Dimensional Higgs Representations
Alfredo Aranda, J. Lorenzo Diaz-Cruz, Alma D. Rojas
In the framework of supersymmetric Grand Unified Theories, the minimal Higgs sector is often extended by introducing multi-dimensional Higgs representations in order to obtain real…
A method of diagonalization for sfermion mass matrices
Alfredo Aranda, J. Lorenzo Diaz-Cruz, R. Noriega-Papaqui
We present a method of diagonalization for the sfermion mass matrices of the minimal supersymmetric standard model (MSSM). It provides analytical expressions for the masses and mix…
Lepton Flavour Violating Heavy Higgs Decays Within the nuMSSM and Their Detection at the LHC
J. L. Diaz-Cruz, Dilip Kumar Ghosh, S. Moretti
Within the MSSM, a Minimal Supersymmetric neutrino See-saw Model, Lepton Flavour Violating Higgs couplings are strongly enhanced at large ($\gsim30$), which can lead to…
On the Feasibility of a Stop NLSP in Gravitino Dark Matter Scenarios
J. L. Diaz-Cruz, John Ellis, Keith A. Olive +1
We analyze the possibility that the lighter stop {\tilde t_1} could be the next-to-lightest supersymmetric particle (NLSP) in models where the gravitino is the lightest supersymmet…
Electroweak-Higgs Unification in the Two Higgs Doublet Model: Masses and Couplings of the Neutral and Charged Higgs Bosons
J. L. Diaz-Cruz, A. Rosado
We obtain the mass spectrum and the Higgs self-coupling of the two Higgs doublet model (THDM) in an alternative unification scenario where the parameters of the Higgs potential $λ_…
