Microstate renormalization in deformed D1-D5 SCFT

We derive the corrections to the conformal dimensions of twisted Ramond ground states in the deformed two-dimensional N=(4,4) superconformal (T4)N/SN orbifold theory describing bound states of the D1-D5 brane system in type IIB superstring theory. Our result holds to second order in the deformation...

Description
Summary:We derive the corrections to the conformal dimensions of twisted Ramond ground states in the deformed two-dimensional N=(4,4) superconformal (T4)N/SN orbifold theory describing bound states of the D1-D5 brane system in type IIB superstring theory. Our result holds to second order in the deformation parameter, and at the large N planar limit. The method of calculation involves the analytic evaluation of integrals of four-point functions of two R-charged twisted Ramond fields and two marginal deformation operators. We also calculate the deviation from zero, at first order in the considered marginal perturbation, of the structure constant of the three-point function of two Ramond fields and one deformation operator.
