Radiation of Closed Strings between the Parallel Dynamical-Dressed Unstable Dp-Branes
Abstract
We introduce a boundary state which is corresponding to a Dp-brane with tangential dynamics in the presence of the Kalb-Ramond field, a tachyonic field and a U(1) gauge potential in a special gauge. From the interaction of such branes radiation amplitude of a general massless closed string will be computed. The effects of the large distances of the branes on this radiation will be studied. In the large distances of the branes, the possibility of axion radiation will be investigated. Our calculations will be in the context of the bosonic string theory.
