Abstract

Exotic hadrons made of five quarks (pentaquarks) are searched for in hadronic Z decays collected by the ALEPH detector at LEP. No significant signal is observed. At 95% C.L., upper limits are set on the production rates N of such particles and their charge-conjugate state per Z decay: N Theta(1535)+ . BR(Theta(1535)^+ -> pK0s < 6.2 x 10^-4, N Xi(1862)-- . BR(Xi(1862)^-- -> xi^- pi^-) < 4.5 x 10^-4, N Xi(1862)^0 . BR(Xi(1862)^0 -> Xi^-pi^+ < 8.9 x 10^-4, N Theta_c(3100)^0 . BR(Theta_c(3100)^0 -> D*-p) < 6.3 x 10^-4, N Theta_c(3100)^0 . BR(Theta_c(3100)^0 -> D^-p) < 31 x 10^-4.
