Hyperon

[3] The first research into hyperons happened in the 1950s and spurred physicists on to the creation of an organized classification of particles.

[6] Today, research in this area is carried out on data taken at many facilities around the world, including CERN, Fermilab, SLAC, JLAB, Brookhaven National Laboratory, KEK, GSI and others.

Physics topics include searches for CP violation, measurements of spin, studies of excited states (commonly referred to as spectroscopy), and hunts for exotic forms such as pentaquarks and dibaryons.

For Ω⁻ as well as the lighter hyperons this decay mode is not possible given the particle masses and the conservation of flavor and isospin necessary in strong interactions.

An exception to this is the Σ⁰ which decays electromagnetically into Λ on account of carrying the same flavor quantum numbers.
