Book Description
We present results for the decays of psi(3100) into baryon and hyperon final states. The sample studied here consists of 1.3 million produced psi decays. The decays into nonstrange baryons agree well with currently established results, but with better statistics. In addition, significant resonance formation in multibody final states is observed. The decay psi .-->. anti pp.gamma., the first direct photon decay of the psi involving baryons in the final state, is presented and the theoretical implications of the decays are briefly explored. Several new decays of the psi involving strange baryons are explored, including the first observations of three body final states involving hyperons. The I-spin symmetry of the strong decay psi .-->. baryons has clearly been observed. The reduced matrix elements for psi .-->. B anti B are presented for final states of different SU(3) content. The B anti B8 results are in excellent agreement with the psi being an SU(3) singlet as are the results for psi .-->. B10 anti B10. We present the first evidence for the SU(3) violating decays of the type psi .-->. B8 anti B10 + c.c. Angular distributions for psi .-->. B8 anti B8 are presented and compared with theoretical predictions. Statistics are limited, but the data tends to prefer other than a 1 + Cos2theta distribution.
