Little Higgs Models and Their Phenomenology
This article reviews the Little Higgs models of electroweak symmetry breaking and their phenomenology. Little Higgs models incorporate a light composite Higgs boson and remain perturbative until a scale of order 10 TeV, as required by precision electroweak data. The collective symmetry breaking mechanism, which forms the basis of Little Higgs models, is introduced. An explicit, fully realistic ...
متن کاملPhenomenology of the Little Higgs model with X-Parity
In the popular littlest Higgs model, T-parity can be broken by Wess-Zumino-Witten (WZW) terms induced by a strongly coupled UV completion. On the other hand, certain models with multiple scalar multiplets (called moose models) permit the implementation of T-parity such that it is not broken by the WZW terms. Here we present a concrete realization of such a model, and discuss the phenomenology a...
متن کاملHiggs Phenomenology with CPsuperH
The MSSM contains CP-violating phases that may have important observable effects in Higgs physics. We review recent highlights in Higgs phenomenology obtained with the code CPsuperH, a useful tool for studies of the production, mixing and decay of a coupled system of the neutral Higgs bosons at future high energy colliders such as the LHC, ILC (γLC), and a muon collider (MC). CPsuperH implement...
متن کاملLittle or No Higgs
Higgsless models offer the possibility of electroweak symmetry breaking without the introduction of any explicit additional Higgs fields in the action within the extra dimensional framework. The various symmetries are broken via the application of appropriately chosen boundary conditions(BC) on the 5D gauge field wavefunctions. The role of the Goldstone bosons is played by the additional scalar...
متن کاملLittle Higgs Dark Matter
The introduction of T parity dramatically improves the consistency of Little Higgs models with precision electroweak data, and renders the lightest T-odd particle (LTP) stable. In the Littlest Higgs model with T parity, the LTP is typically the T-odd heavy photon, which is weakly interacting and can play the role of dark matter. We analyze the relic abundance of the heavy photon, including its ...
