Minimal Supersymmetric Standard Model
i.e. SM particles plus two Higgs doublets and their SUSY partners
Even this minimal spectrum can have many faces:
Is R-parity conserved?
- Is the LSP (lightest supersymmetric particle) stable?
How is supersymmetry broken?
- Supergravity-inspired (mSUGRA): the typical benchmark
- parameters m1/2, m0, A0, tan b, sign(m)
- radiative EWSB occurs naturally from large top mass
- the c01 is the LSP
- c01 , c02 , c?1 , sleptons and h are “light”
- c03 , c04 , c?2 , squarks and gluinos are “heavy”
- Gauge-mediated (GMSB): LSP can be Gravitino
- signatures with photons and/or slow-moving particles which may decay within or outside detector
- Anomaly mediated
- lightest chargino and neutralino almost degenerate
