Search for pentaquark states in Z decays
A search for exotic baryons containing five quarks has been carried out in hadronic Z decays using the ALEPH detector at LEP I. No significant signal has been found. Preliminary Limits are set, at the 95% confidence level, on the following production rates per hadronic Z decay: N_Theta(1535)(+) <...
