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.
