Honours - Exotic Hadrons

Mon., Apr. 3, 2017 3:30 p.m. - Mon., Apr. 3, 2017 4:30 p.m.

Location: CL 125

Abstract: Since the discovery that neutrons and protons are comprised of quarks there has been a goal to find other hadronic states in order to better understand how they work. Because of the many baryonic and mesonic states discovered the goal has been to look for more exotic states like tetraquarks and pentaquarks. These are states which are comprised of more quark and antiquarks than normal hadrons seen so far. This talk will start with looking at a historical attempt, the Θ+, at finding a pentaquark state. Then we will look at some potential tetraquark states found by the Belle collaboration and confirmed by other collaborations. Lastly two pentaquark states found by the LHCb collaboration will be discussed.
