Abstract:
Twenty years ago, in 2003, two experimental groups, LEPS and DIANA announced the discovery of a light, narrow, exotic baryon with mass within the range of 1540~MeV, which was later dubbed as Theta^+. In this talk we recall the history of this discovery and its theoretical foundations. We also discuss possible future experiments that could determine the existence of Theta+.
Important: This seminar is held in building D-11 room 104.
