Constraining fine tuning in Composite Higgs Models with partially composite leptons
James Barnard, Daniel Murnane, Martin White +1
Minimal Composite Higgs Models (MCHM) have long provided a solution to the hierarchy problem of the Standard Model, yet suffer from various sources of fine tuning that are becoming…
Parton Shower Uncertainties in Jet Substructure Analyses with Deep Neural Networks
James Barnard, Edmund Noel Dawe, Matthew J. Dolan +1
Machine learning methods incorporating deep neural networks have been the subject of recent proposals for new hadronic resonance taggers. These methods require training on a datase…
Long-Lived, Colour-Triplet Scalars from Unnaturalness
James Barnard, Peter Cox, Tony Gherghetta +1
Long-lived, colour-triplet scalars are a generic prediction of unnatural, or split, composite Higgs models where the spontaneous global-symmetry breaking scale TeV a…
Collider constraints on tuning in composite Higgs models
James Barnard, Martin White
Two potential sources of tuning exist in composite Higgs models: one comes from keeping the Higgs VEV below the compositeness scale and one comes from keeping the Higgs light after…
The Unnatural Composite Higgs
James Barnard, Tony Gherghetta, Tirtha Sankar Ray +1
Composite Higgs models can trivially satisfy precision-electroweak and flavour constraints by simply having a large spontaneous symmetry breaking scale, f > 10 TeV. This produces a…
A simple technique for combining simplified models and its application to direct stop production
James Barnard, Ben Farmer
The results of many LHC searches for supersymmetric particles are interpreted using simplified models, in which one fixes the masses and couplings of most sparticles then scans ove…
