SEMINAR       Wednesday, 19th November 2003 - h. 12:00  Aula A1       Nora Brambilla Univ. di Milano        "Heavy Quarkonium and Effective Field Theories of QCD"           Abstract QCD nonrelativistic effective field theories (NREFT) are the modern and most suitable frame to describe heavy quarkonium properties. In this talk I summarize some of the most recent developments and physical applications (spectrum, decays, production) of NREFT.
