Supersymmetry and integrability of the elliptic $AdS_{3} \times S^{3} \times T^{4}$ superstring

Ben Hoare, Fiona K. Seibold

We construct a 1-parameter family of Ramond-Ramond fluxes supporting the elliptic $AdS_{3} \times S^{3} \times T^{4}$ metric with constant dilaton and preservi…

Elliptic deformations of the $AdS_{3} \times S^{3} \times T^{4}$ string

Ben Hoare, Ana L. Retore, Fiona K. Seibold

With the aim of investigating the existence of an integrable elliptic deformation of strings on $AdS_{3} \times S^{3} \times T^{4}$ , we compute the tree-level…

AdS3 Integrability, Tensionless Limits, and Deformations: A Review

Fiona K. Seibold, Alessandro Sfondrini

Motivated by the recent advances in the understanding of integrability for $A d S_{3}$ backgrounds, we present a lightning review of this approach, with particular attention to the "te…

Interpolating families of integrable AdS3 backgrounds

Fiona K. Seibold, Alessandro Sfondrini

We construct families of integrable deformations that interpolate between $A d S_{3} \times S^{3} \times S^{3} \times S^{1}$ and either $A d S_{3} \times S^{3} \times S^{2} \times T^{2}$ or $AdS_3\times S^2…

Scattering on the supermembrane

Fiona K. Seibold, Arkady A. Tseytlin

We compute the one-loop $2 \to 2$ scattering amplitude of massless scalars on the world volume of an infinite $D = 11$ supermembrane quantized in the static gauge. The resu…

S-matrix on effective string and compactified membrane

Fiona K. Seibold, Arkady A. Tseytlin

Expanding Nambu-Goto action near infinitely long string vacuum one can compute scattering amplitudes of 2d massless fields representing transverse string coordinates. As was shown…
