Pion masse
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.
