Light Composite Higgs: Lch @ Lhc
Here I summarize some of the salient features of technicolor theories with technifermions in higher dimensional representations of the technicolor gauge group. The expected phase diagram as function of number of flavors and colors for the two index (anti)symmetric representation of the gauge group is reviewed. After having constructed the simplest walking technicolor theory one can show that it...
متن کاملLight exotic Higgs bosons at the LHC
Most models of new physics contain extended Higgs sectors with multiple Higgs bosons. The observation of an additional Higgs boson, besides the ∼ 125 GeV ‘hobs’, will thus serve as an irrefutable evidence of physics beyond the Standard Model (SM). However, even when fairly light, these additional Higgs bosons may have escaped detection at the Large Electron-Positron (LEP) collider, the Tevatron...
متن کاملMinimal Composite Higgs Model with Light Bosons
We analyze a composite Higgs model with the minimal content that allows a light Standard-Model-like Higgs boson, potentially just above the current LEP limit. The Higgs boson is a bound state made up of the top quark and a heavy vector-like quark. The model predicts that only one other bound state may be lighter than the electroweak scale, namely a CP-odd neutral scalar. Several other composite...
متن کاملSupersymmetric LHC phenomenology without a light Higgs boson
After a brief discussion of the mass of the Higgs in supersymmetry, I introduce λSUSY, a model with an extra chiral singlet superfield in addition to the MSSM field content. The key features of the model are: the superpotential W = λSHdHu with a large coupling λ and the resulting lightest Higgs with mass above 200GeV. The main part of my contribution will be about how λSUSY manifests itself at ...
متن کاملLight Higgs Searches at the Lhc Using Jet Substructure
One of the major goals of the LHC is to discover the Higgs boson, which is the only particle of the Standard Model (SM) that has not been seen yet at colliders. Even if we cannot predict its mass, SM precision electroweak fits seem to favour a low-mass Higgs,2 and LEP data excluded a mass below 114 GeV.3 That’s why we are going to focus on the search for a light Higgs boson at the LHC, assuming...
