For a short-correlated Gaussian velocity field the problem of the passive scalar with the imposed constant gradient is considered. It is shown that the scaling of the three-point correlation function is anomalous. In the limit of large dimension of space d, the anomalous exponent is calculated. © 1996 The American Physical Society.
