Absorption by Double - Centered D 3 - Branes and the Coulomb Branch of N = 4 SYM Theory

چکیده
We calculate the classical cross-section for absorption of a minimally coupled scalar in the double-centered D3-brane geometry. The dual field theory has gauge symmetry broken to S(U(N1) × U(N2)) and is on the Coulomb branch of N = 4 Super Yang-Mills theory. Our analysis is valid at energy scales much smaller than the W particles mass, giving logarithmic corrections to the cross section calculated at the IR conformal fixed points. These corrections are associated with deformations of the N = 4 Super Yang-Mills theory by irrelevant operators that break conformal invariance and correspond to processes where a virtual pair of gauge particles or a virtual pair of W bosons interact with the incident wave to create a pair of gauge particles.

On the central charge extension of the N = 4 SYM spin chain
In this paper it is argued that the central charge extension of the Coulomb branch of N = 4 SYM theory appears as a limit of Beisert’s central charge extension of the planar N = 4 spin chain in the presence of boundaries. These boundaries are interpreted as D-branes that source the central charge and are realized as giant gravitons and dual giant gravitons in the AdS dual. The BPS states that c...
متن کاملD3-brane shells to black branes on the Coulomb branch
We use the AdS/CFT duality to study the special point on the Coulomb branch of N = 4 SU(N) gauge theory which corresponds to a spherically symmetric shell of D3-branes. This point is of interest both because the spacetime region inside the shell is flat, and because this configuration gives a very simple example of the transition between D-branes in the perturbative string regime and the nonper...

In the present paper we study S(N) → S(U (N/2) × U (N/2)) symmetry breaking in N = 4 SY M via AdS/CFT correspondence. We consider two stacks of N/2 parallel D3 branes separated by a distance 2 d. In this case there is mixing between the different l-wave dilatonic KK modes. We calculate certain the two point correlation functions in the dual gauge theory. Due to mode mixing, the diagonal correla...

We study SU (N) → S(U (N/2) × U (N/2)) symmetry breaking in N = 4 SY M via AdS/CFT correspondence. Two stacks of N 2 parallel D3 branes are separated by a distance 2d in the transverse directions. This leads to an interaction between different l-wave dilatonic KK modes when expanded in S 5 harmonics. We calculate certain two point correlation functions of the dual gauge theory in the decoupling...
