Radiation of a massless closed string from interacting Dp-branes with background fields in the superstring theory.

In the context of the superstring theory, we calculate the radiation amplitude of a general massless closed string from the interaction of two parallel D p -branes. The background field is the constant antisymmetric tensor B μ ν , and the branes have been equipped with the different U (1) gauge fields. For the large distance of the branes, the Kalb-Ramond emission will be investigated. [ABSTRACT FROM AUTHOR]
