Title: On the asymptotic states and the quantum S matrix of the η-deformed AdS₅ × S⁵ superstring

Abstract

We investigate the worldsheet S matrix of string theory in η-deformed AdS₅ × S⁵. By computing the six-point tree-level S matrix we explicitly show that there is no particle production at this level, as required by the classical integrability of the theory. At one and two loops we show that integrability requires that the classical two-particle states be redefined in a non-local and η-dependent way. This is a significant departure from the undeformed theory which is probably related to the quantum group symmetry of the worldsheet theory. We use generalized unitarity to carry out the loop calculations and identify a set of integrals that allow us to give a two-loop Feynman integral representation of the logarithmic terms of the two-loop S matrix. We finally also discuss aspects of the calculation of the two-loop rational terms.

The AdS{sub 5}xS{sup 5} superstring worldsheet S matrix and crossing symmetry

Journal Article Janik, Romuald A - Physical Review. D, Particles Fields

An S matrix satisfying the Yang-Baxter equation with symmetries relevant to the AdS{sub 5}xS{sup 5} superstring recently has been determined up to an unknown scalar factor. Such scalar factors are typically fixed using crossing relations; however, due to the lack of conventional relativistic invariance, in this case its determination remained an open problem. In this paper we propose an algebraic way to implement crossing relations for the AdS{sub 5}xS{sup 5} superstring worldsheet S matrix. We base our construction on a Hopf-algebraic formulation of crossing in terms of the antipode and introduce generalized rapidities living on the universal cover of themore »« less

One-loop matrix elements of effective superstring interactions: α'-expanding loop integrands

Journal Article Edison, Alex ; Guillen, Max ; Johansson, Henrik ; ... - Journal of High Energy Physics (Online)

In the low-energy effective action of string theories, non-abelian gauge interactions and supergravity are augmented by infinite towers of higher-mass-dimension operators. We propose a new method to construct one-loop matrix elements with insertions of operators D^2kFⁿ and D^2kRⁿ in the tree-level effective action of type-I and type-II superstrings. Inspired by ambitwistor string theories, our method is based on forward limits of moduli-space integrals using string tree-level amplitudes with two extra points, expanded in powers of the inverse string tension α'. Similar to one-loop ambitwistor computations, intermediate steps feature non-standard linearized Feynman propagators which eventually recombine to conventional quadratic propagators. Withmore »« less

Scale invariance of the η -deformed AdS 5 × S 5 superstring, T-duality and modified type II equations

Journal Article Arutyunov, G. ; Frolov, S. ; Hoare, B. ; ... - Nuclear Physics. B

We consider the ABF background underlying the η-deformed AdS₅ × S⁵ sigma model. This background fails to satisfy the standard IIB supergravity equations which indicates that the corresponding sigma model is not Weyl invariant, i.e. does not define a critical string theory in the usual sense. We argue that the ABF background should still define a UV finite theory on a flat 2d world-sheet implying that the η-deformed model is scale invariant. This property follows from the formal relation via T-duality between the η-deformed model and the one defined by an exact type IIB supergravity solution that has 6 isometriesmore »« less

Half-BPS Wilson loop and AdS 2 /CFT 1

Journal Article Giombi, Simone ; Roiban, Radu ; Tseytlin, Arkady A. - Nuclear Physics. B

Here, we study correlation functions of local operator insertions on the 1/2-BPS Wilson line in N=4 super Yang–Mills theory. These correlation functions are constrained by the 1d superconformal symmetry pre-served by the 1/2-BPS Wilson line and define a defect CFT₁ living on the line. At strong coupling, a set of elementary operator insertions with protected scaling dimensions correspond to fluctuations of the dual fundamental string in AdS₅×S⁵ ending on the line at the boundary and can be thought of as light fields propagating on the AdS₂ worldsheet. We use AdS/CFT techniques to compute the tree-level AdS₂ Witten diagrams describing themore »« less
