String corrections to circular Wilson loop and anomalies
Alessandra Cagnazzo, Daniel Medina-Rincon, Konstantin Zarembo
We study string quantum corrections to the ratio of latitude and circular Wilson loops in N=4 super-Yang-Mills theory at strong coupling. Conformal gauge for the corresponding mini…
An Integrability Primer for the Gauge-Gravity Correspondence: an Introduction
Diego Bombardelli, Alessandra Cagnazzo, Rouven Frassek +7
We introduce a series of articles reviewing various aspects of integrable models relevant to the AdS/CFT correspondence. Topics covered in these reviews are: classical integrabilit…
Spectra of Sigma Models on Semi-Symmetric Spaces
Alessandra Cagnazzo, Volker Schomerus, Vaclav Tlapak
Sigma models on semi-symmetric spaces provide the central building block for string theories on AdS backgrounds. Under certain conditions on the global supersymmetry group they can…
High-Gradient Operators in the psl(2|2) Gross-Neveu Model
Alessandra Cagnazzo, Volker Schomerus, Václav Tlapák
It has been observed more than 25 years ago that sigma model perturbation theory suffers from strongly RG-relevant high-gradient operators. The phenomenon was first seen in 1-loop…
On the Spectrum of Superspheres
Alessandra Cagnazzo, Volker Schomerus, Vaclav Tlapak
Sigma models on coset superspaces, such as odd dimensional superspheres, play an important role in physics and in particular the AdS/CFT correspondence. In this work we apply recen…
Integrability and Wilson loops: the wavy line contour
A. Cagnazzo
The Wilson loop with a wavy line contour is studied using integrable methods. The auxiliary problem is solved and the Lax operator is built to first order in perturbation theory, c…
