Susy’s Swansong When first Feynman wrote down his QED The loop corrections to the boson mass And associated sins of naturalness Were surely faults that he could not forsee, Which motivate a supersymmetry That cancels out the top unpleasantness Only to introduce an utter mess Of sparticles, conserved R-parity: Alas! For though the theorists are keen (The neutralino’s a dark candidate) No scrap of evidence has yet been seen Constraining parameter space of late This incessant model building might mean We leave poor Susy to her grisly fate.
