- CLEO decided to study the various bottom and charm quarkonia states and charm mesons.
- Quarkonia are bound states of heavy flavour quarks ( charm or bottom ) and their antiquarks.
- Work is also being done on calculations of such properties as widths of quarkonia states and transition rates between the states.
- Grasping the wealth of experimental results requires understanding the medium modification of quarkonia and disentangling hot and cold-matter effects.
- An early, but still effective, technique uses models of the " effective " potential to calculate masses of quarkonia states.
