Abstract
The effect of long-range random static fields on classical diffusion is investigated. It is shown that the long-range component of random fields leads to the appearance of a new (compared to the white noise case) fixed point in the renormalisation group equations. The critical exponents and oscillating corrections corresponding to the new fixed point are calculated.Keywords
