TOPQUARK
Top quark
The top quark, also known as the t quark or truth quark, is an elementary particle and a fundamental constituent of matter. Like all quarks, the top quark is an elementary fermion with spin-spin-½, and experiences all four fundamental interactions: gravitation, electromagnetism, weak interactions, and strong interactions. It has an electric charge of + e, and is the most massive of all observed elementary particles. It has a mass of 173.07 ± 0.52 ± 0.72, which is about the same mass as an atom of tungsten. The antiparticle of the top quark is the top antiquark, which differs from it only in that some of its ...The above text is a snippet from Wikipedia: Top quark
