WebThe upsilon particle is a meson which was discovered at Fermilab in 1977. It appeared as another long-lived particle which didn't fit into the framework of the first four quarks, the up, down, strange, and charm … WebUsing detectors equipped with special photographic emulsion that can record the tracks of charged particles, the physicists at Bristol found the decay of a heavier meson into a lighter one. They called the heavier particle π (or pi), and it has since become known as the pi-meson, or pion.
In particle physics, a pion (or a pi meson, denoted with the Greek letter pi: π ) is any of three subatomic particles: π , π , and π . Each pion consists of a quark and an antiquark and is therefore a meson. Pions are the lightest mesons and, more generally, the lightest hadrons. They are unstable, with the … See more Theoretical work by Hideki Yukawa in 1935 had predicted the existence of mesons as the carrier particles of the strong nuclear force.
