Constructs Little Higgs models from simple groups that generate the Higgs quartic coupling through collective symmetry breaking, extending the theory-space approach to new group-theoretic structures.
Int. J. Mod. Phys. A 20 (2005) 7412-7422
Studies the potential of electron-electron collisions to probe the spectrum and couplings of the Littlest Higgs model.
unpublished
Studies composite vector mesons in the context of the Little Higgs program, connecting QCD-like dynamics to the gauge boson partners predicted by theory-space models.
Phys. Rev. D 69:065022 (2004)
Investigates the scalar dark matter candidate in the Little Higgs theory-space model, performing a thermal relic density calculation and finding two viable mass regions — around 100 GeV and above 500 GeV — where the dark matter is an admixture of SU(2) triplet and singlet.

Studies precision electroweak constraints on the SU(6)/Sp(6) Little Higgs model, identifying a near-oblique limit and finding viable parameter space with top partners as light as 1 TeV and W' as light as 1.8 TeV.
Phys. Rev. D 69 (2004) 035002
Constructs a Little Higgs model with custodial SU(2) as an approximate symmetry, based on a modification of the Minimal Moose with SO(5) global symmetries. Achieves small contributions to precision electroweak observables with a breaking scale as low as 700 GeV and accessible TeV-scale partners.

Nucl. Phys. B Proc. Suppl. 117 (2003) 728-730
Conference proceedings summarizing the Little Higgs approach to the hierarchy problem, where the Higgs is a pseudo-Goldstone boson protected by collective symmetry breaking.

Extends the deconstruction program to six-dimensional gauge theories using two-dimensional moose lattices, studying the strongly coupled dynamics and their relation to continuum 6D theories.
JHEP 0208:019 (2002)
Shows that the fundamental group of theory space determines all relevant classical physics in the low-energy theory of Little Higgs models, providing a systematic method for constructing theory spaces with any desired particle content and potential.
JHEP 0208:021 (2002)
Introduces the minimal theory-space construction for a Little Higgs model, where the Higgs is a pseudo-Goldstone boson protected from quadratic divergences by collective symmetry breaking. Predicts new TeV-scale partners for the top quark, gauge bosons, and scalars, with the entire Higgs potential generated by the top Yukawa coupling.
JHEP 0208:020 (2002)
Works out the collider phenomenology and dark matter implications of the Little Higgs mechanism, predicting light Higgs doublets accompanied by new weak triplet and singlet scalars, heavy TeV-scale particles with distinctive decay signatures, and a new WIMP dark matter candidate from a discrete geometric symmetry.
