Abstract

Samples of ∼1,900 identified protons and ∼500 Λ have been used to search for decuplet baryon production in e+e- annihilation at a c.m. energy of 34.4 GeV. The p π+ and Λ π± invariant mass spectra contain no Δ or Σ* signals. Upper limits, at 95% confidence level, are that less than 12% of all p and less than 26% of all Λ come from the decay of doubly charged Δ and singly charged Σ* states respectively. These limits correspond to production rates of ++ and ± per event (inclusive of anti-particles). Production of the decuplet states Δ++ and Σ*± is suppressed by a factor ≳9 relative to octet baryons of the same strangeness.
