History • Murray Gell-Mann and Yuval Ne´eman postulated in 1964 that hadrons can be constructed from a number of fundamental particles called 'quarks'. • almost at the same time George Zweig proposed the same idea and he coined the fundamental particles 'aces'. Simela Aslanidou 14.12.2006
History • both, Gell-Mann and Zweig, chose the SU(3)-symmetry (flavour)group theory to organise the increasing number of discovered particles. • they made their predictions on the basis of the known baryon and meson octets. • in their theory of SU(3)-symmetry (flavor) they could organize all known hadrons as states of three different constituents.
