In 1960, Vernon Hughes discovered a system in which an electron circled a positive one of these.
In 1960, Vernon Hughes discovered a system in which an electron circled a positive one of these. Extremely unstable, they only exist for a few millionths of a second, quickly decaying into electrons or positrons with less than 1/200 of the original mass, along with several neutrinos. FTP, identify this particule, whose existence was proposed in 1935 by Hideki Yukawa, which was discovered a year later by Carl Anderson.
