Abstract

The tachyon effective field theory describing the dynamics of a non-BPS D-p-brane has electric flux tube solutions where the electric field is at its critical value and the tachyon is at its vacuum. It has been suggested that these solutions have the interpretation of fundamental strings. We show that in order that an electric flux tube can "end" on a kink solution representing a BPS D-(p-1)-brane, the electric flux must be embedded in a tubular region inside which the tachyon is finite rather than at its vacuum where it is infinite. Energetic considerations then force the transverse "area" of this tube to vanish. We suggest a possible interpretation of the original electric flux tube solutions around the tachyon vacuum as well as of tachyon matter as system of closed strings at a density far above the Hagedorn density.
