Towards an Understanding of the Correlations in Jet Substructure

Eur. Phys. J. C 75 (2015) 409

Report from the BOOST 2013 workshop studying relationships between jet substructure observables, their complementarity, and their dependence on underlying jet properties for quark/gluon discrimination, boosted W tagging, and boosted top tagging.

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.

Learning How to Count: A High Multiplicity Search for the LHC

JHEP 08 (2013) 136

Introduces a subjet-counting search technique for high-multiplicity BSM signals at the LHC, using jet substructure to count subjets within large-radius jets and demonstrating improved sensitivity across eight benchmark signals with reduced reliance on missing energy.

High Multiplicity Searches at the LHC Using Jet Masses

Phys. Rev. D 85 (2012) 055029

Introduces a new class of BSM searches that recluster events into large-radius fat jets and require multiple massive jets, improving sensitivity to high-multiplicity signals including R-parity violating gluino decays by 20-50% in mass reach.

Heavy Flavor Simplified Models at the LHC

JHEP 01 (2012) 074

Develops a comprehensive set of simplified models for LHC final states with top and bottom quarks, optimizing search strategies for pair-produced color octets and triplets, and providing benchmarks that ensure optimal coverage of heavy flavor new physics.

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unpublished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.

Simplified Models for LHC New Physics Searches

J. Phys. G 39 (2012) 105005

A systematic catalog of simplified models for new-physics searches at the LHC, defining minimal effective Lagrangians with few new particles whose masses and cross-sections map directly to observable quantities. Output of the SLAC workshop on Topologies for Early LHC Searches.

Jet Dipolarity: Top Tagging with Color Flow

JHEP 04 (2012) 007

Introduces dipolarity, a jet observable that distinguishes whether a pair of subjets originates from a color-singlet source by measuring the pattern of radiation between them. Incorporated into the HEPTopTagger, it improves top-vs-QCD discrimination.

Bigger, Better, Faster, More at the LHC

JHEP 12 (2010) 030

Develops search strategies for new physics at the LHC that improve sensitivity by combining multiple signal regions and optimizing for broad coverage across simplified model mass planes.

The Hunt for New Physics at the Large Hadron Collider

Nucl. Phys. Proc. Suppl. 200-202 (2010) 185-417

A comprehensive overview of new physics possibilities at the LHC, covering electroweak symmetry breaking, dark matter, extra dimensions, supersymmetry, hidden sectors, and TeV-scale strings, intended as a companion to the ATLAS and CMS Technical Design Reports.

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.

Model-Independent Jets plus Missing Energy Searches

Phys. Rev. D 79 (2009) 015005

Proposes a model-agnostic approach to jets + missing energy searches at the LHC by defining kinematic bins and publishing differential cross-section limits that can be reinterpreted for any BSM model producing the same final state.

Searching for Gluinos at the Tevatron and Beyond

Int. J. Mod. Phys. A 23 (2008) 4637-4646

Conference proceedings reviewing search strategies for gluinos at the Tevatron and the upcoming LHC, summarizing the model-independent approach to jets plus missing energy searches.

Stopping Gluinos

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.

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.
