A P-Brane vindication of the two Higgs-doublet minimally super-symmetric standard model and related issues

The two-Higgs doublet MSSM predicts three neutral and two charged Higgs particles. The present work gives a vindication of this model based on a P-Brane model in eleven dimensions. Subsequently, we give alternative derivations using various ideas from the theory of maximally symmetric spaces and E-Infinity theory.
