Prof. Carlo Rubbia,Italian physicist at the CERN particle physics laboratory,Geneva. He won the 1984 Nobel Prize for physics for his role in the 1983 discovery of the W & Z particles,which are the mediators of the weak nuclear force. They were discovered at the giant UA1 detector built by Rubbia's team at CERN. The photo shows Rubbia with a computer display of a Z particle event from UA1. The Z itself lives too briefly to be visible,but its existence is deduced from the 2 muons (white tracks) into which it decays along with other particles (yellow & green tracks). Rubbia was born in 1934 at Gorizia,on the Italian-Yugoslav border. Photo was taken at CERN in September 1984 | |
