The Zamolodchikov-Faddeev Algebra for AdS_5 x S^5 Superstring
Gleb Arutyunov, Sergey Frolov, Marija Zamaklar
We discuss the Zamolodchikov-Faddeev algebra for the superstring sigma-model on AdS_5 x S^5. We find the canonical su(2|2)^2 invariant S-matrix satisfying the standard Yang-Baxter…
The Off-shell Symmetry Algebra of the Light-cone AdS_5 x S^5 Superstring
Gleb Arutyunov, Sergey Frolov, Jan Plefka +1
We analyze the psu(2,2|4) supersymmetry algebra of a superstring propagating in the AdS_5 x S^5 background in the uniform light-cone gauge. We consider the off-shell theory by rela…
Finite-size Effects from Giant Magnons
Gleb Arutyunov, Sergey Frolov, Marija Zamaklar
In order to analyze finite-size effects for the gauge-fixed string sigma model on AdS_5 x S^5, we construct one-soliton solutions carrying finite angular momentum J. In the infinit…
On highest-energy state in the su(1|1) sector of N=4 super Yang-Mills theory
G. Arutyunov, A. A. Tseytlin
We consider the highest-energy state in the su(1|1) sector of N=4 super Yang-Mills theory containing operators of the form tr(Z^{L-M} ψ^M) where Z is a complex scalar and ψis a com…
