Abstract
About three million hadronic decays of the Z collected by ALEPH in the years 1991 to 1994 are used to search for anomalous Cp violation beyo nd the Standard Model in the decay Z-->b(b) over barg$. The study is p erformed by analyzing angular correlations between the two quarks and the gluon in three-jet events and by measuring the differential two-je t rate. No signal of CP violation is found. For the combinations of an omalous CP violating couplings, (h) over cap(b)$=<(h)over cap (Ab)g(Vb )>-<(h)over cap (Vb)g(Ab)> and h(b)=root<(h)over cap (2)(Vb)>+<(h)ove r cap (2)(Ab)>, limits of \(h) over cap(b)$\<0.59 and h(b)<3.02 are g iven at 95% CL.
