Top quark Top quark The top quark, also known as the t quark (symbol: t) or truth quark, is the most massive of all observed elementary particles. Like all quarks, the top quark is a fermion with spin , and experiences all four fundamental interactions: gravitation, electromagnetism, weak interactions, and strong interactions. It has an electric charge of + "e". It has a mass of 172.44 ± 0.13 (stat) ± 0.47 (syst), which is about the same mass as an atom of tungsten. The antiparticle of the top quark is the top antiquark (symbol: , sometimes called "antitop quark" or simply "antitop"),
