Title: Exotic hadrons with heavy quarks

Speaker: Prof. Jean-Marc Richard (University of Lyon, France)

Time: 3:30PM, January 31st (Thur.)

Place: Theory Division，319

Abstract:

We review some mechanisms possibly leading to the existence of multiquark hadrons, that are stable, i.e., lying below the threshold for spontaneous dissociation into two ordinary hadrons. This includes heavy tetraquarks with charm C=2 or beauty B=-2, and some higher configurations. We also discuss some production mechanisms.
