Can the 126 GeV boson be a pseudoscalar?
Baradhwaj Coleppa, Kunal Kumar, Heather E. Logan
We test the possibility that the newly-discovered 126 GeV boson is a pseudoscalar by examining the correlations among the loop-induced pseudoscalar decay branching fractions to $γγ…
High-energy suppression of the Higgsstrahlung cross-section in the Minimal Composite Higgs Model
Katy Hartling, Heather E. Logan
If the Higgs boson is composite, signs of this compositeness should appear via a formfactor-like suppression of Higgs scattering cross sections at momentum transfers above the comp…
Discovering Strong Top Dynamics at the LHC
R. Sekhar Chivukula, Baradhwaj Coleppa, Pawin Ittisamai +4
We analyze the phenomenology of the top-pion and top-Higgs states in models with strong top dynamics, and translate the present LHC searches for the Standard Model Higgs into bound…
Constraints on large scalar multiplets from perturbative unitarity
Katy Hally, Heather E. Logan, Terry Pilkington
We determine the constraints on the isospin and hypercharge of a scalar electroweak multiplet from partial-wave unitarity of tree-level scattering diagrams. The constraint from SU(…
