The Higgs - a fundamental particle?
prof. dr hab. David Blaschke
The LHC experiments ATLAS and CMS have reported the observation of a
previously unknown boson with a mass between 125 and 127 GeV, whose
behaviour so far has been consistent with the Higgs boson of the
Standard Model (previous IFT seminar by L. Turko). After reviewing the
concept of the Standard Model Higgs, I will present some alternative
models where the scalar Higgs boson is not a fundamental but rather a
composite particle. Particularly interesting seem concepts where the
role of the Higgs field is played by strongly bound pairs of fermions,
e.g., so-called techniquarks (technicolor models) or top quarks (top
quark condensate). This discussion will be presented from a
non-insider perspective owing to the actuality of the problem.
