The discovery of a Higgs boson at the LHC represents a monumental step towards understanding the origin of electroweak symmetry breaking. Its mass around 125 GeV has important implications for different models of electroweak symmetry breaking. Supersymmetry prefers a light Higgs boson, but a Higgs mass of 125 GeV is in some tension with the predictions of the minimal supersymmetric standard model (MSSM). Either at least one of the superpartners of the top quark is quite heavy, which reintroduces the naturalness problem, or there should be some ad- ditional contribution to the Higgs quartic coupling, which requires extensions beyond the minimal supersymmetric standard model.
Another possibility is that the Higgs boson is a bound state of new dynamics becoming strong at a scale not much far above the weak scale. Models in which the Higgs boson is a composite state have attracted increasing interest in recent years, among both the theoretical and experimental communities engaged with the LHC discovery program. At least two distinct theoretical paradigms are being pursued for composite Higgs: models in which the Higgs is realized as a pseudo-Nambu-Goldstone boson (PNGB), and top-condensate models.
The purpose of the Composite Higgs Program is to bring together the experts in the field, and to stimulate discussions on theories of Composite Higgs and their experimental signatures at the LHC.
We encourage the participants to spend about ten days or so within the Fermilab Theoretical Physics Department, but shorter visits are also possible. The Program will host about ten people per week. Each participant will be provided with office space, and rooms are reserved for discussions and collaboration. During this event, we will have about one seminar each day on theoretical aspects of composite Higgs models, plus a couple of talks per week on topics more related to the experimental field.
