Abstract
We calculate the effect of noncommutative spacetime on the greybody factor on the supergravity side. For this purpose we introduce a system of D3-branes with a constant NS B field along their world volume directions ${(x}_{2}{,x}_{3}).$ Considering the propagation of a minimally coupled scalar with nonzero momentum along ${(x}_{2}{,x}_{3}),$ we derive an exact form of the greybody factor in the B field. It turns out that ${\ensuremath{\sigma}}_{l}^{B\ensuremath{\ne}0}>{\ensuremath{\sigma}}_{l}^{B=0}.$ This means that the presence of the B field (the noncommutativity) suppresses the potential barrier surrounding the black hole. As a result, the greybody factor increases.
