NS5-brane backgrounds and coset CFT partition functions
Andrea Dei, Emil J. Martinec
Worldsheet string theory is solvable for a variety of backgrounds involving Neveu-Schwarz fivebranes, in terms of gauged nonlinear sigma models on group manifolds. We compute the w…
String correlators on : Analytic structure and dual CFT
Andrea Dei, Lorenz Eberhardt
We continue our study of string correlators on Euclidean with pure NS-NS flux. The worldsheet and spacetime correlators have a rich analytic structure, which we anal…
String correlators on : Four-point functions
Andrea Dei, Lorenz Eberhardt
We propose a closed-form formula for genus 0 four-point functions in string theory with pure NS-NS flux including arbitrary amounts of spectral flow. Our formula pas…
String correlators on : Three-point functions
Andrea Dei, Lorenz Eberhardt
We revisit the computation of string worldsheet correlators on Euclidean with pure NS-NS background. We compute correlation functions with insertions of spectrally f…
Stress-energy tensor correlators from the world-sheet
Hanno Bertle, Andrea Dei, Matthias R. Gaberdiel
The large limit of symmetric orbifold theories was recently argued to have an AdS/CFT dual world-sheet description in terms of an WZW model. In pr…
Free field world-sheet correlators for
Andrea Dei, Matthias R. Gaberdiel, Rajesh Gopakumar +1
We employ the free field realisation of the world-sheet theory to constrain the correlators of string theory on ${\rm AdS}_3\times {\rm S}^3\times \mathbb…
Correlators of the symmetric product orbifold
Andrea Dei, Lorenz Eberhardt
We exploit null vectors of the fractional Virasoro algebra of the symmetric product orbifold to compute correlation functions of twist fields in the large limit. This yields a…
Three-point functions in AdS/CFT holography
Andrea Dei, Lorenz Eberhardt, Matthias R. Gaberdiel
Recently, string theory on with one unit of NS-NS flux () was argued to be exactly dual to the symmetric orbifold of $ \ma…
Integrable S matrix, mirror TBA and spectrum for the stringy WZW model
Andrea Dei, Alessandro Sfondrini
We compute the tree-level bosonic S matrix in light-cone gauge for superstrings on pure-NSNS . We show that it is pr…
Integrable spin chain for stringy Wess-Zumino-Witten models
Andrea Dei, Alessandro Sfondrini
Building on arXiv:1804.01998 we investigate the integrable structure of the Wess-Zumino-Witten (WZW) model describing closed strings on . Using the recen…
The plane-wave limit of
Andrea Dei, Matthias R. Gaberdiel, Alessandro Sfondrini
The plane-wave limit of is analysed for generic null-geodesics that are not necessarily BPS. For the case of pure N…
