Unification and Dark Matter in a Minimal Scalar Extension of the Standard Model

unpublished

Explores gauge coupling unification and dark matter in a minimal extension of the Standard Model with additional scalar fields, studying the interplay between unification constraints and the dark matter relic density.

D-terms, Unification, and the Higgs Mass

JHEP 0606:034 (2006)

Shows that gauge extensions of the MSSM with non-decoupling D-terms can raise the Higgs boson mass while maintaining gauge coupling unification, with unification constraining the Higgs mass to below roughly 150 GeV and predicting new heavy gauge bosons at a few TeV.
