UPSILON spectroscopy
Description
A summary is presented on radiative decays of the UPSILON(1S) and UPSILON(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 UPSILON(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 UPSILON(2S) resonance to the 3Pj 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 UPSILON states are an ideal testing ground for the theory of strong interactions. 58 refs
