The S parameter for a Light Composite Higgs: a Dispersion Relation Approach
Axel Orgogozo, Slava Rychkov
We derive a dispersion relation for the S parameter in the SO(5)/SO(4) Minimal Composite Higgs model. This generalizes the Peskin-Takeuchi formula to the case when a light Higgs bo…
What if the Higgs couplings to W and Z bosons are larger than in the Standard Model?
Adam Falkowski, Slava Rychkov, Alfredo Urbano
We derive a general sum rule relating the Higgs coupling to W and Z bosons to the total cross section of longitudinal gauge boson scattering in I=0,1,2 isospin channels. The Higgs…
Exploring T and S parameters in Vector Meson Dominance Models of Strong Electroweak Symmetry Breaking
Axel Orgogozo, Slava Rychkov
We revisit the electroweak precision tests for Higgsless models of strong EWSB. We use the Vector Meson Dominance approach and express S and T via couplings characterizing vector a…
EWSB Theory on the Eve of Higgs Boson Exclusion/Discovery
Slava Rychkov
A personal feeling of where we stand theoretically in the puzzle of EWSB, faced with the impressive limits on new physics set at the summer conferences. Plenary talk at EPS HEP 201…
Signals of composite electroweak-neutral Dark Matter: LHC/Direct Detection interplay
Riccardo Barbieri, Slava Rychkov, Riccardo Torre
In a strong-coupling picture of ElectroWeak Symmetry Breaking, a composite electroweak-neutral state in the TeV mass range, carrying a global (quasi-)conserved charge, makes a plau…
Radiation Problem in Transplanckian Scattering
Paolo Lodone, Slava Rychkov
We investigate hard radiation emission in small-angle transplanckian scattering. We show how to reduce this problem to a quantum field theory computation in a classical background…
