Bing doubling is an operation which produces a 2–component boundary link from a knot . If is slice, then is easily seen to be boundary slice. In this paper, we investigate whether the converse holds. Our main result is that if is boundary slice, then is algebraically slice. We also show that the Rasmussen invariant can tell that certain Bing doubles are not smoothly slice.
