Higher Derivative Corrections in Holographic QCD
We consider the effect of the R4 term in type IIA string theory on the supergravity background dual to Nc D4 branes compactified on a circle with supersymmetry breaking boundary conditions. We study the dynamics of D8 branes in this perturbed geometry in the probe approximation. This leads to an analysis of higher derivative corrections in holographic QCD beyond the supergravity approximation. ...
متن کاملAdS3, Black Holes and Higher Derivative Corrections
Using AdS/CFT correspondence and the Euclidean action formalism for black hole entropy Kraus and Larsen have argued that the entropy of a BTZ black hole in three dimensional supergravity with (0,4) supersymmetry does not receive any correction from higher derivative terms in the action. We argue that as a consequence of AdS/CFT correspondence the action of a three dimensional supergravity with ...
متن کاملEnhanced Coset Symmetries and Higher Derivative Corrections
After dimensional reduction to three dimensions, the lowest order effective actions for pure gravity, M-theory and the Bosonic string admit an enhanced symmetry group. In this paper we initiate study of how this enhancement is affected by the inclusion of higher derivative terms. In particular we show that the coefficients of the scalar fields associated to the Cartan subalgebra are given by we...
متن کاملHigher Derivative Corrections, Dimensional Reduction and Ehlers Duality
Motivated by applications to black hole physics and duality, we study the effect of higher derivative corrections on the dimensional reduction of four-dimensional Einstein, Einstein-Liouville and Einstein-Maxwell gravity to one direction, as appropriate for stationary, spherically symmetric solutions. We construct a field redefinition scheme such that the one-dimensional Lagrangian is corrected...
متن کاملFuzzball geometries and higher derivative corrections for extremal holes
2-charge D1-D5 microstates are described by geometries which end in ‘caps’ near r = 0; these caps reflect infalling quanta back in finite time. We estimate the travel time for 3-charge geometries in 4-D, and find agreement with the dual CFT. This agreement supports a picture of ‘caps’ for 3-charge geometries. We argue that higher derivative corrections to such geometries arise from string windi...
