Abstract
Let B-0, B-1, ... , B-n be independent standard Brownian motions, starting at 0. We investigate the tail of the capture time tau (n), = inf {t > 0 : B-i (t) - b(i) = B-0 (t) for some 1 less than or eq ual to i less than or equal to n} where 0 < b(i) less than or equal to 1, 1 < i less than or equal to n. In p articular, we have E tau (3) = infinity and E tau (5) < infinity. Various g eneralizations are also studied.
