Constraining new coloured matter from the ratio of 3- to 2-jets cross sections at the LHC
Diego Becciolini, Marc Gillioz, Marco Nardecchia +2
The Large Hadron Collider experiments are probing the evolution of the strong coupling up to the TeV scale. We show how the ratio of 3- to 2-jets cross sections is affected b…
Vector-like Bottom Quarks in Composite Higgs Models
Marc Gillioz, Ramona Grober, Andreas Kapuvari +1
Like many other models, Composite Higgs Models feature the existence of heavy vector-like quarks. Mixing effects between the Standard Model fields and the heavy states, which can b…
Standard Model Vacuum Stability and Weyl Consistency Conditions
Oleg Antipin, Marc Gillioz, Jens Krog +2
At high energy the standard model possesses conformal symmetry at the classical level. This is reflected at the quantum level by relations between the different beta functions of t…
a New Conformal Window Bound from the a theorem
Oleg Antipin, Marc Gillioz, Francesco Sannino
We propose a novel constraint on the gauge dynamics of strongly interacting gauge theories stemming from the a theorem. The inequality we suggest is used to provide a lower bound o…
Higgs Low-Energy Theorem (and its corrections) in Composite Models
M. Gillioz, R. Grober, C. Grojean +2
The Higgs low-energy theorem gives a simple and elegant way to estimate the couplings of the Higgs boson to massless gluons and photons induced by loops of heavy particles. We exte…
Dangerous Skyrmions in Little Higgs Models
Marc Gillioz
Skyrmions are present in many models of electroweak symmetry breaking where the Higgs is a pseudo-Goldstone boson of some strongly interacting sector. They are stable, composite ob…
The Little Skyrmion: New Dark Matter for Little Higgs Models
Marc Gillioz, Andreas von Manteuffel, Pedro Schwaller +1
We study skyrmions in the littlest Higgs model and discuss their possible role as dark matter candidates. Stable massive skyrmions can exist in the littlest Higgs model also in abs…
One light composite Higgs boson facing electroweak precision tests
Marc Gillioz
We study analytically and numerically the bounds imposed by the electroweak precision tests on a minimal composite Higgs model. The model is based on spontaneous SO(5)/SO(4) breaki…
