Y spectroscopy
- 1. Wuerzburg Univ. (Germany, F.R.)
Description
A summary is presented on radiative decays of the Y(1S) and Y(2S) states as measured by the detectors ARGUS, CLEO, Crystal Ball and CUSB operating at the storage rings CESR and DORIS II. In particular, the search for heavy mass states below the Y(1S) resonance is discussed. Nothing (un)expected in the form of gluonium, supersymmetric particles or Higgs bosons has shown up yet. Also covered are transitions from the Y(2S) resonance to the 3P-J bottonium states which have been measured with high precision. The spins of those states are shown to be consistent with expectation. Comparison with potential models yields information on the interquark force. It is argued that the Y states are an ideal testing ground for the theory of strong interactions. (orig.)
