摘要：

We have shown that the renormalization group fixed point for mutually avoiding directed random walks in (d + 1) dimensions is exactly 2-pi-epsilon where epsilon = 2 - d, with no higher order terms in epsilon. Since the whole calculation can be carried out to all orders exactly, the model is also significant from a pedagogical point of view.
