It is unique among particles of its kind in that it does not hadronize, and therefore decays into a W boson and bottom quark, as seen in its discovery with the Tevatron accelerator in 1995 at Fermilab.
Along with its lighter partner, it was predicted by Kobayashi and Maskawa, who deduced its existence from CP-violation in neutral kaons. Produced predominately in pairs after high-energy collisions between protons and antiprotons, this subatomic particle, which possesses a two-thirds charge, is sufficiently heavy that perturbative QCD could be used to give a theoretical estimate of its mass. It is unique among particles of its kind in that it does not hadronize, and therefore decays into a W boson and bottom quark, as seen in its discovery with the Tevatron accelerator in 1995 at Fermilab. With a mass of about 174 GeV, for ten points, name this heaviest and last-discovered quark, the partner of the bottom quark.
