Diagonal symmetries beyond the standard model.
Batra, Puneet.

Diagonal symmetries beyond the standard model. - 62 p.

Advisers: Savas Dimopoulos; David E. Kaplan.

Thesis (Ph.D.)--Stanford University, 2004.

We use diagonal symmetries to address experimental and conceptual shortcomings of theories "Beyond the Standard Model". We first show that embedding the Weak gauge group, SU(2)W, as the diagonal subgroup of a gauged SU(2) x SU(2) symmetry can open up dramatic new regions of parameter space for Supersymmetric models: regions where the CP-even Higgs mass is as large as &sim;350 GeV (Chapter 2), where tan beta < 1 (Chapter 3), and where the lightest Higgs state is charged (Chapter 3). In Chapter 4 we show that a Little Higgs theory (with a gauged SU(12) diagonal symmetry) can form the Ultraviolet completion for another Little Higgs theory (with a gauged SU(4) diagonal symmetry). This theory remains perturbative up to 100 TeV and allows for further structural extensions to yet higher cutoffs---all without introducing quadratic instability in the Weak scale.
