About three million hadronic decays of the Z collected by ALEPH in the years 1991 to 1994 are used to search for anomalous violation beyond the Standard Model in the decay . The study is performed by analyzing angular correlations between the two quarks and the gluon in three-jet events and by measuring the differential two-jet rate. No signal of violation is found. For the combinations of anomalous violating couplings, and , limits of and are given at 95% CL.
