Flavor Problem, Proton Decay And Neutrino Oscillations In SUSY Models With Anomalous
Qaisar Shafi, Zurab Tavartkiladze
We discuss how realistic supersymmetric models can be constructed by employing an anomalous flavor symmetry which also mediates supersymmetry breaking. A judicious ch…
Bi-maximal Neutrino Mixings And Proton Decay In SO(10) With Anomalous Flavor
Qaisar Shafi, Zurab Tavartkiladze
By supplementing supersymmetric SO(10) with an anomalous flavor symmetry and additional `matter' superfields carrying suitable charges, we explain the c…
R-Parity Violation: Origin of -Term and Other Consequences
Qaisar Shafi, Zurab Tavartkiladze
We propose a new mechanism in which the generation of the supersymmetric -term as well charged lepton masses is closely tied to R-parity violation involving heavy vector-like fa…
An Improved Supersymmetric SU(5)
Qaisar Shafi, Zurab Tavartkiladze
By supplementing minimal supersymmetric SU(5) (MSSU(5)) with a flavor symmetry and two pairs of `matter' supermultiplets, we present an improved model w…
Proton Decay, Neutrino Oscillations And Other Consequences From Supersymmetric SU(6) With Pseudo-Goldstone Higgs
Qaisar Shafi, Zurab Tavartkiladze
We suggest a new mechanism for naturally suppressing dimension five baryon number violating in supersymmetric SU(5+N) (N=0, 1,...) GUTs. The mechanism is realized through suppressi…
Neutrino Mixings and Fermion Masses in Supersymmetric SU(5)
Qaisar Shafi, Zurab Tavartkiladze
We consider neutrino mixings in supersymmetric SU(5) supplemented by a U(1) flavor symmetry. In particular, we show how bi-maximal neutrino mixings can be realized. Two scenarios f…
