Курс лекций по физике бозона Хиггса

Образование, 27 сентября 2016

Приглашаем на курс лекций по физике бозона Хиггса «Higgs mechanism in the Standard Model and beyond», состоящий из 6 семинаров. Семинары пройдут 1-3 и 8-10 ноября 2016 г. с 10:00 до 12:00 конференц-зале Лаборатории ядерных проблем.

Лектор: И.П. Иванов (CFTP, Instituto Superior Tecnico, U. Lisboa)

Темы семинаров 1-3 ноября:

  • Overview: electroweak theory and the role(s) of the Higgs mechanism. Hopes from bSM. Higgs mechanisms (insights into fermion properties, CP violation, FCNC). A very brief history.
  • Abelian Higgs model: giving mass to the gauge boson; giving mass to the fermion, basic properties of the Higgs boson.
  • Full electroweak theory and the Brout-Englert-Higgs mechanism:
    • electroweak lagrangian before EWSB and symmetries,
    • massive W and Z,
    • the ρ-parameter and custodial symmetry,
    • masses and mixing of fermions within SM,
    • a brief outline of the SM Higgs boson properties.

Темы семинаров 8-10 ноября:

  • EWSB in terms of gauge-invariant quantities, Elitzur’s theorem.
  • More than one Higgs doublet:
    • Higgs mechanism in MSSM: initial lagrangian, minimizing potential and tan β, physical Higgs spectrum: h, H, A, H ± , their couplings to other particles, very brief remarks on phenomenology.
    • Inert doublet model: a simplest model with symmetry-protected DM candidate.
    • Several Higgses in fermion sector: lepton-flavour-violatiing decays, flavour-changing neutral coupling. Recent hints on H → μτ and deviations in b → s«.
  • Short intro in models with Higgs singlets or higher representations.
  • Short intro in Higgs sectors in models with higher gauge groups (with the example of 331 model).
