Supersymmetry is a theoretical concept in physics that postulates the existence of a symmetry between particles that have integer spin, such as photons and gluons (known as bosons), and those that have half-integer spin, such as electrons and quarks (known as fermions).
According to supersymmetry, for every known fundamental particle in the Standard Model of particle physics, there exists a corresponding, yet-to-be-discovered "superpartner" particle with a different spin. For example, the superpartner of an electron would be a particle called a selectron, and the superpartner of a photon would be a particle called a photino.
Supersymmetry is an attempt to solve some of the outstanding problems in particle physics, such as the hierarchy problem and the nature of dark matter. However, so far, no superpartners have been observed, and experiments at the Large Hadron Collider (LHC) have constrained the possible masses and properties of these hypothetical particles.
