S - wave absorption of scalars by noncommutative D 3 - branes
On the supergravity side, we study the propagation of the RR scalar and the dilaton in the D3-branes with NS B-field. To obtain the noncommutative effect, we consider the case of B → ∞(θ → π/2). This corresponds to the black D-string background. In this background, the RR scalar induces an instability of the near-horizon geometry. However, it turns out that the RR scalar is nonpropagating, whil...
متن کاملScalar Absorption by Noncommutative D3-branes
The classical cross section for low energy absorption of the RRscalar by a stack of noncommutative D3-branes in the large NS B-field limit is calculated. In the spirit of AdS/CFT correspondence, this cross section is related to two point function of a certain operator in noncommutative Yang-Mills theory. Compared at the same gauge coupling, the result agrees with that of obtained from ordinary ...
متن کاملAbsorption of Fermions by D3-branes
The absorption cross section of fermions by D3-branes is calculated by means of both classical D = 7, N = 4 supergravity and the effective gauge field theory on their worldvolume. The two methods give the same results, supporting the microscopic description of black holes in terms of D-branes and giving another evidence of AdS/superconformal reciprocity. 1 E-mail: [email protected]...
متن کاملScalar absorption by spinning D3-branes
We discuss absorption of scalars by a distribution of spinning D3-branes. The D3-branes are multi-center solutions of supergravity theory. We solve the wave equation in various cases of supergravity backgrounds in which the equation becomes separable. We show that the absorption coefficients exhibit a universal behavior as functions of the angular momentum quantum number and the Hawking tempera...
متن کاملS-wrapped D3-branes on Conifolds
We construct a D3-brane wrapped on S, which is fibred over the resolved conifold as its transverse space. Whereas a fractional D3-brane on the resolved conifold is not supersymmetric and has a naked singularity, our solution is supersymmetric and regular everywhere. We also consider an S-wrapped D3-brane on the resolved cone over T /Z2, as well as on the deformed conifold. In the former case, w...
