The Standard Theory of Fundamental Interactions 50 years after J/ψ discovery: From Charmonium to the Exotic Hadrons

Wednesday 13 Mar 2024, 15:15 → 17:00 Europe/Rome

Aula A (Dipartimento di Fisica)

Speaker: Luciano Maiani

Abstract

Starting from the November Revolution initiated  in 1974 by the discovery of J/$\psi$, I will illustrate the progress made with the Standard Theory in the theoretical description of hadrons as quark-antiquark  and three quark states (mesons and baryons, respectively). In 2003, the discovery of the X(3872) meson opened a new chapter, the so-called exotic hadrons, not fitting in the previous picture and presumably made by four or five quarks: Tetraquarks and Pentaquarks. I will describe recent progress in this field, arriving to the latest studies in Roma and CERN of hidden charm and double charm tetraquarks.
