We discuss the embedding of R-Parity preserving Minimal Left Right Supersym-metric models into Pati-Salam and SO(10) GUTs.

Termites and ants contribute more to animal biomass in tropical rain forests than any other single group and perform vital ecosystem functions. Although ants prey on termites, at the community level the linkage between these groups is poorly understood. Thus, assessing the distribution and specificity of ant termitophagy is of considerable interest. We describe an approach for quantifying ant-t...

We discuss the fermion mass problem in SUSY GUTs, including such ideas as texture zeroes, and Georgi-Jarlskog textures. We focus on a specific supersymmetric model based on the gauge group SU(4)⊗SU(2)L ⊗SU(2)R. In this model the gauge group is broken to that of the standard model at 10 GeV, and supersymmetry is broken at low-energy. The model may be regarded as a “surrogate SUSY GUT”, and has s...

A Supersymmetric Grand unified model is constructed based on SO(10)xSO(10) symmetry in which new types of Yukawa matrices couple standard and exotic fermions. Evolution of these couplings from the Grand Unified scale to the electroweak scale causes some of them to be driven to their fixed points. This solves the supersymmetric alignment problem and ensures that there are no observable flavor ch...
