SUSY model building for a 126 GeV Higgs

Particle Physics Theory seminar

SUSY model building for a 126 GeV Higgs

  • Event time: 2:00pm
  • Event date: 22nd April 2014
  • Speaker: Moritz McGarrie (Wits University)
  • Location: Higgs Centre Seminar Room,

Event details

This talk will explore two possible models which can achieve the correct Higgs mass and still allow for sparticles accessible to the LHC's reach. In the first example we built two tailor made spectrum generators to analyse a Higgs extension (non decoupled D-terms) of the MSSM, based on quiver gauge theories. We then explore the LHC & ILC's capability to determine their effect through their enhancement of Higgs branching ratios with respect to the Standard Model.  In the second Model, we use the NMSSM to obtain the correct Higgs mass and then explore flavour-gauge mediation to obtain light 3rd generation squarks, whilst keeping the 1st and 2nd generation above exclusions. Both models are also realisable through magnetic SQCD. I will hopefully also discuss further avenues for model building opportunities in the context of Natural SUSY.

Event resources

The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
