Closed string radiation from the interacting fractional-dressed Dp-branes with the transverse motions
We determine the boundary states, associated with a fractional D p -brane in the presence of the Kalb–Ramond field and a U (1) gauge potential. The background spacetime is the non-compact orbifold R 1 , 21 ⊗ R 4 / Z 2 . Besides, the brane has a transverse velocity. We compute the radiation amplitude...

. Besides, the brane has a transverse velocity. We compute the radiation amplitude of a massless closed string from the interaction of two fractional D
p
-branes with the previous background fields. The branes have been dressed by different fields and have transverse motions. The total radiation amplitude will be investigated for large inter-brane separation. Finally, the graviton, Kalb–Ramond (axion) and dilaton emissions will be distinctly studied. Our calculations are in the context of the bosonic string theory. |
