Production of Missing cc and bb States
Stephen Godfrey, Jonathan L. Rosner
Abstract
The heavy quarkonium cc and bb resonances have a rich spectroscopy with numerous narrow S, P, and D-wave levels below the production threshold of open charm and beauty mesons. The mass predictions for these states are an important test of QCD calculations. We review some recent work describing the production of missing ηb(nS), 13DJ(bb) and 11P1(cc) and 11P1(bb) states.
