Compares the physics reach of 14, 33, and 100 TeV proton colliders using SUSY simplified models as benchmarks, contributing to the community assessment of future collider options.
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.

Studies the possibility of light gluinos with R-parity violating decays at the Tevatron, exploring reconstruction techniques for these challenging multijet final states.
unpublished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.

Proposes a class of supersymmetric composite dark matter models where Standard Model interactions communicate SUSY breaking to the dark sector, computing the bound state spectrum with leading supersymmetry effects using a general formalism independent of binding dynamics.

Reinterprets the first ATLAS supersymmetry search with 70/nb of data, showing that gluino masses below 205 GeV are disfavored regardless of LSP mass, already surpassing the Tevatron reach for compressed spectra.

Studies the spectrum of supersymmetric bound states, computing degeneracies in supersymmetric hydrogen and emphasizing the general features of non-relativistic supersymmetric bound state systems.
Phys. Lett. B 666 (2008) 34-37
Shows how to search the complete kinematic parameter space for pair-produced color octets decaying to two jets plus missing energy at the Tevatron, demonstrating that CMSSM-motivated cuts cause existing searches to miss discoverable spectra.

Phys. Rev. D 75:085006 (2007)
Shows that in a class of supersymmetric models with metastable vacua, the transition to a lower-energy state does not occur even for arbitrarily high reheating temperatures, contrary to naive expectations about thermal transitions between vacua.
Phys. Rev. D 76 (2007) 055007
Shows that long-lived gluinos in split supersymmetry form R-hadrons that stop in detector material, with 10^6 stopping per year in LHC detectors for a 300 GeV gluino. The subsequent delayed decays produce distinctive calorimeter deposits with no tracker or muon chamber activity.
Phys. Rev. D 72 (2005) 075011
Derives an upper limit on scalar superpartner masses in split supersymmetry from big bang nucleosynthesis constraints on long-lived gluinos. A TeV-mass gluino must decay within 100 seconds, setting the SUSY breaking scale below 10^9 GeV.
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.
Phys. Rev. D 70:117703 (2004)
Computes one-loop predictions for split supersymmetry, finding the Higgs mass in the range 130-170 GeV for scalar masses above 10^6 GeV, and showing that 1% measurements of gaugino couplings could determine the SUSY breaking scale to within an order of magnitude.
JHEP 0203:055 (2002)
Provides an explicit formulation of supersymmetric Yang-Mills theories from 5 to 10 dimensions in familiar 4D N=1 superspace, enabling systematic model building with extra dimensions, orbifold constructions, brane-localized interactions, and anomaly inflow.
