Abstract
When unstable Dp-branes in type-II string theory are placed in a B-field, the resulting tachyonic world-volume theory becomes non commutative. We argue that for large noncommutativity parameter, condensation of the tachyon as a non-commutative soliton leads to new decay modes of the Dp-brane into (p-2)-brane configurations, which we interpret as suitably smeared BPS D(p-1)-branes. Some of these configurations are metastable. We discuss various generalizations of this decay process.
