squark
Quick Summary
A squark is a hypothetical particle in physics that is the boson analogue of a quark, as postulated by supersymmetry. Supersymmetry is a complex mathematical framework that proposes a symmetry between fermions (particles like quarks and leptons) and bosons (particles like photons and gluons). This theory suggests that every known fundamental particle has a "superpartner" with different spin properties. For example, a squark would be the supersymmetric partner of a quark. While quarks are fundamental constituents of matter, squarks are theoretical particles that have not yet been experimentally detected. If squarks exist, they are predicted to be significantly heavier than quarks.1234
