Abstract

A sample of 3.73 million hadronic Z decays, recorded with the OPAL detector at LEP in the years 1991.95. has been used to search for a narrow resonance corresponding to the decay of the D*(/+/-)(2629) meson into D*(+/-)pi (+)pi (-). The D*(+) mesons are reconstructed in the decay channel D*(+) --> D(0)pi (+) with D-0 --> K(-)pi (+). No evidence for a narrow D*(/+/-)(2629) resonance is found. A limit on the production of narrow D*(/+/-)(2629) in hadronic Z decays is derived: f(Z --> D*(/+/-)(2629)) x Br(D*(/+) --> D*(+)pi (+)pi (-)) <3.1 x 10(-3)(95%C.L.).
