We determine the boundary states, associated with a fractional Dp-brane in the presence of the Kalb–Ramond field and a U(1) gauge potential. The background spacetime is the non-compact orbifold . Besides, the brane has a transverse velocity. We compute the radiation amplitude of a massless closed string from the interaction of two fractional Dp-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.
