Instructor: Nicolaos Toumbas, Fotios Ptochos
• The shortcomings of the Standard Model & the advantages of Supersymmetry (SUSY). A qualitative presentation.
• Weyl, Dirac and Majorana Spinors
• Supersymmetric Algebra, generators and superfields; SUSY transformations
• Structure of SUSY theories: Superpotential, gauge interactions, derivation of Langrangian, F and D terms. SUSY vacuum and spontaneous breaking of SUSY
• Wess – Zumino Model (superpotential, interactions, cancellation of the quadratic divergencies, particle spectrum)
• The Minimal SUSY Standard Model (MSSM): Structure of the superpotential, interactions, unification of the gauge coupling constants, R-parity, soft-SUSY breaking terms
• Renormalization-group Equations for the gauge and Yukawa coupling constants, and the soft SUSY breaking terms: Derivation and solution
• The Higgs sector of MSSM: The scalar sector, the violation of the electroweak gauge symmetry and the spectrum of the Higgs particles
• SUSY spectrum of MSSM: Squarks, Sleptons, Neutralinos, Charginos, Gluinos
• Interactions of MSSM: Tree-level calculations, decay and production of SUSY particles, phephenomenological and cosmological implications (qualitative approach).
• Variants of MSSM – Numerical packages (SoftSUSY, Suspect and MicrOmegas)
• Restriction of the parametric space of MSSM: Mass of the lighter CP-even Higgs boson, rare decays of the B meson, relic abundance of the Lightest SUSY particle (LSP).
