(8398) Rubbia Main-belt Asteroid
Discovered on 12 December 1993 by Farra d'Isonzo at Farra d'Isonzo.
Named in honor of the Italian physicist Carlo Rubbia (b. 1934), winner of the 1984 Nobel Prize in physics for his decisive contribution to the large project that led to the discovery of the field particles W and Z, communicators of weak interaction. His discovery has supplied a fundamental check of the unified theory of electro-weak interactions. He is the fourth Italian Nobel laureate in physics.Naming citation (19990202/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
