PLACE: Kenkyu Honkan 2F RM 220
TITLE: Composite Higgs Physics

SPEAKER: Prof. Christophe Grojean  (CERN)
LANGUAGE: English
ABSTRACT: A basic question the LHC will address concerns the strength of the new dynamics at the origin of electroweak symmetry breaking: is the force behind this symmetry breaking a weak or a strong one? This question is thought to be equivalent to asking whether a light Higgs boson exists or not. However, a light Higgs boson can also emerge as a composite state from a strong sector. I will discuss the physics of such models, focussing on the collider signatures at the LHC and the future ILC. ReferenceĦ§JHEP 0706:045 (2007), hep-ph/0703164
