Search for narrow resonances in e+e- annihilation at c.m. energies between 33.0 and 36.72
Abstract
A search for narrow resonances in e+e- annihilation between 33.00 and 36.72 GeV is reported. No evidence is found for the existence of such states. The 90% confidence upper limit on the integrated resonance cross section is determined to be 28 nb MeV, a value significantly below that expected for the lowest tt bound state.
