Rubbia, Carlo

Italian physicist who in 1984 shared with Simon van der Meer the Nobel Prize for Physics for the discovery of the massive, short-lived subatomic W particle and Z particle. These particles are the carriers of the so-called weak force involved in the radioactive decay of atomic nuclei. Their existence strongly confirms the validity of the electroweak theory, proposed in the 1970s, that the weak force and electromagnetism are different manifestations of a single basic kind of physical interaction.
