“…The higher interaction terms generate perturbations of the D-brane state that should cause instabilities at higher string energies. Since our objective is finding the D-brane states, we shall limit our analysis in the rest of this paper to the first order perturbation from (6). The boundary states obtained in this limit are called semiclassical D-branes.…”

Abstract:In this paper we discuss the existence of quantum D-brane states in the strong gravitational field and in the presence of a constant Kalb-Ramond field. A semiclassical string quantization method in which the spacetime metric AB and the constant antisymmetric Kalb-Ramond field AB are treated exactly is employed. In this framework, the semiclassical D-branes are defined at the first order perturbation around the trajectory of the center-of-mass of a string. The set of equations the semiclassical D-branes must satisfy in a general strong gravitational field are given. These equations are solved in the A S background where it is shown that a D-brane coherent state exists if the operators that project the string fields onto the corresponding Neumann and Dirichlet directions satisfy a set of algebraic constraints. A second set of equations that should be satisfied by the projectors in order that the semiclassical state be compatible with the global structure of the D-brane are derived in the particle limit of a string in the torsionless A S background. 11.25.Db; 11.25.Uv.

The gauge/gravity correspondence for non‐supersymmetric theories

Abstract: Abstract:We review the string construction of the "orientifold field theories" and we show that for these theories the gauge/gravity correspondence is only valid for a large number of colours.
