Abstract. The self intersection local time of d-dimensional Brownian motion requires a regularization for d>=3. We can then expand it in terms of Wick ordered products of white noise. In this note we show that. after a multiplicative renormalization, each term of this expansion convergees in law to a Brownian motion when the regularization is removed.
