tasilectures: weak scale supersymmetry — a top-motivated-bottom-up approach

◦ Introduction, Perspective – since particle physics beyond the SM is presently in an incoherent state, with lots of static, a long introduction is needed, including some history of the supersymmetry revolutions, physics not described by the SM, indirect evidence for low energy supersymmetry and how flavor physics should be approached. ◦ Derive the supersymmetric Lagrangian – the superpotential W ◦ Soft supersymmetry breaking – underlying physics – Lsoft – the MSSM ◦ The μ opportunity – R-parity conservation ◦ Count of parameters – constraints – measuring the parameters ◦ Connecting the weak and unification scale ◦ Derivation of the Higgs mechanism – in what sense does supersymmetry explain the Higgs physics ◦ The Higgs spectrum – tanβ, Yukawa couplings, constraints ◦ LEP Higgs physics – Tevatron Higgs physics can confirm the Higgs mechanism and coupling proportional to mass – Higgs sector measurements ◦ g̃, Ñ, C̃ – cannot in general measure tanβ at hadron colliders ◦ Effects of soft phases – all observables, not only CPV ones, gμ − 2, EDMs, g̃ phase, LSP CDM, possible connections to stringy physics ◦ Phase structure of simple D-brane models ◦ Tevatron superpartner searches, signatures ◦ Extensions of the MSSM ◦ The importance of low scale supersymmetry is not only that we learn of another profound aspect of our world, but also to provide a window to Planck scale physics, in order to connect string theory and our world
