LABORATORI NAZIONALI DI FRASCATI
Speaker: Luciano Maiani (La Sapienza Univ.) The discovery of two pentaquarks by LHCb has reinforced the case of “exotic’ hadrons, which have diquarks and antidiquarks as basic units. I review the cases studied until now, the so called XYZ states, the theoretical basis for this concept and the implications for the existence of further states, with baryon number equal two.
