Giant magnon solution and dispersion relation in string theory in AdS_3 x S^3 x T^4 with mixed flux
B. Hoare, A. Stepanchuk, A. A. Tseytlin
We address the question about the exact form of the dispersion relation for light-cone string excitations in string theory in AdS3 x S3 x T4 with mixed R-R and NS-NS 3-form fluxes.…
Weyl anomaly of conformal higher spins on six-sphere
A. A. Tseytlin
This paper is a sequel to arXiv:1309.0785 were we computed the Weyl anomaly a-coefficient on d-sphere for higher-derivative conformal higher spin field in d=4 and shown that it mat…
On partition function and Weyl anomaly of conformal higher spin fields
A. A. Tseytlin
We study 4-dimensional higher-derivative conformal higher spin (CHS) fields generalising Weyl graviton and conformal gravitino. They appear, in particular, as "induced" theories in…
One-loop correction to the energy of a wavy line string in AdS_5
E. I. Buchbinder, A. A. Tseytlin
We consider a computation of one-loop AdS_5 x S^5 superstring correction to the energy radiated by the end-point of a string which moves along a wavy line at the boundary of AdS_5…
Massive S-matrix of AdS_3 x S^3 x T^4 superstring theory with mixed 3-form flux
B. Hoare, A. A. Tseytlin
The type IIB supergravity AdS_3 x S^3 x T^4 background with mixed RR and NSNS 3-form fluxes is a near-horizon limit of a non-threshold bound state of D5-D1 and NS5-NS1 branes. The…
On the U(1) duality anomaly and the S-matrix of N=4 supergravity
J. J. M. Carrasco, R. Kallosh, R. Roiban +1
N=4 Poincare supergravity has a global SU(1,1) duality symmetry that acts manifestly only on shell as it involves duality rotations of vector fields. A U(1) subgroup of this symmet…
