Measuring the tth coupling from SSDL+2b measurements

Phys. Rev. D 88 (2013) 093006

Evaluates the potential of a same-sign dilepton plus two b-jet search for tth production, providing direct access to the top Yukawa coupling without dependence on loop-level couplings or Higgs width uncertainties.

Here be Dragons: The Unexplored Continents of the CMSSM

JHEP 09 (2013) 061

Provides a complete map of the CMSSM parameter space consistent with the Higgs mass and dark matter abundance, organizing viable regions by dark matter mechanism and presenting benchmark models with their 13 TeV LHC signatures.

Higgs, Binos and Gluinos: Split Susy Within Reach

unpublished

Shows that early LHC evidence for a Higgs boson at 142-147 GeV points to PeV-scale split supersymmetry, with moderate-lifetime gluinos (25 microns to 10 years decay length) and an almost purely bino LSP at 70 GeV as discovery signatures.

Collective Quartics from Simple Groups

JHEP 06 (2010) 041

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.

Discovering the Higgs with Low Mass Muon Pairs

Phys. Rev. D 79 (2009) 115006

Shows that a Higgs boson decaying to light pseudoscalars can be discovered via the subdominant channel where one pseudoscalar decays to muon pairs, enabling coverage at the Tevatron and early LHC even when the pseudoscalar mass is below 10 GeV.

Four Taus at the Tevatron

Studies extensions of the Standard Model where the Higgs decays via a cascade to four tau leptons and shows that multi-lepton excesses could be visible at the Tevatron with 6 fb^-1 for a 110 GeV Higgs.

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.

Little Higgs and Custodial SU(2)

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.

The Minimal Moose for a Little Higgs

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.

Phenomenology of Electroweak Symmetry Breaking from Theory Space

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.
