英文摘要	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-Xi(1862) (.) BR(Xi(1862)(--) --> Xi(-pi-)) < 4.5 x 10(-4), N-Xi(1862)0 (.) BR(Xi(1862)(0) <8.9 x 10(-4), N-Thetac(3100)0 BR(Theta(c)(3100)(0) D*(-)p) < 6.3 x 10(-4), N-Thetac(3100)0 (.) BR(Theta(c)(3100)(0) --> D- p) < 31 X 10(-4). (C) 2004 Elsevier B.V. All rights reserved.
