An abbreviation in physics: SUSY for supersymmetry

In particle physics, the term SUSY (pronounced ‘Susie’) is a short form for supersymmetry [1-3]. Supersymmetry is a theory: an extension of the Standard Model. SUSY—often addressed as an elegant theory—provides a framework for attempts to unify electromagnetic, weak, strong, and gravitational interactions.

A key feature of SUSY is the prediction of superparticles. The Large Hadron Collider (LHC) [4] at the French-Swiss border near Geneva has the capability to recreate conditions that existed a split second after the Big Bang, during which superparticles should have been created and lasted for a very short time in the nanosecond range. However, particle physicists at LHC, so far, have not been able to detect any superparticles, casting doubt on the theory of supersymmetry. Whatever happens to the theory, the abbreviation SUSY will stay!

Keywords: particle physics, super particles, Large Hadron Collider (LHC)
