75/-- Benefits of supersymmetry:
76
77 1. **Hierarchy problem**: Cancels quadratic divergences
78 2. **Gauge coupling unification**: Couplings meet at ~10¹⁶ GeV
79 3. **Dark matter candidate**: Lightest superpartner (LSP)
80 4. **String theory**: Requires SUSY for consistency -/

90/-- Standard SUSY breaking scenarios:
91
92 1. **Gravity-mediated**: Breaking in hidden sector, gravity transmits
93 2. **Gauge-mediated**: Breaking transmitted by gauge interactions
94 3. **Anomaly-mediated**: Breaking from conformal anomaly
95
96 All involve a "hidden sector" where SUSY breaks. -/
