Seminar
Title: Tetra and pentaquarks in the constituent quark model
Speaker: Prof. Luciano Maiani (Sapienza University of Rome & INFN)
Time: 10:00AM, June 23rd, 2016 (Thursday)
Place: Theoretical Physics Division,319
Abstract:The discovery of two pentaquarks by LHCb have reinforced the case of “exotic’ hadrons, which have diquarks and antidiquarks as basic units. I review (i) the theoretical basis for this concept, in particular recent developments in the 1/N expansio in large N QCD (ii) the implications for the existence of further states, in particular with baryon number equal to two (dibaryons) and (iii) the new data on [c cbar][s sbar] states.
