Higher order RG flow on the Wilson line in SYM

Matteo Beccaria, Simone Giombi, Arkady A. Tseytlin

Extending earlier work, we find the two-loop term in the beta-function for the scalar coupling in a generalized Wilson loop operator of the SYM theory, working…

Exact results in a N=2 superconformal gauge theory at strong coupling

M. Beccaria, M. Billo, M. Frau +2

We consider the SYM theory with gauge group SU() and a matter content consisting of one multiplet in the symmetric and one in the anti-symmetric representation.…

Strong coupling expansion of free energy and BPS Wilson loop in superconformal models with fundamental hypermultiplets

M. Beccaria, G. V. Dunne, A. A. Tseytlin

As a continuation of the study (in arXiv:2102.07696 and arXiv:2104.12625) of strong-coupling expansion of non-planar corrections in 4d superconformal models we consi…

BPS Wilson loop in superconformal "orientifold" gauge theory and weak-strong coupling interpolation

Matteo Beccaria, Gerald V. Dunne, Arkady A. Tseytlin

We consider the expectation value of the circular BPS Wilson loop in superconformal gauge theory containing a vector multiplet coupled…

The Conformal Anomaly Action to Fourth Order (4T) in in Momentum Space

Claudio Corianò, Matteo Maria Maglio, Dimosthenis Theofilopoulos

We elaborate on the structure of the conformal anomaly effective action up to 4-th order, in an expansion in the gravitational fluctuations of the background metric, in the f…

On topological recursion for Wilson loops in SYM at strong coupling

Matteo Beccaria, Azeem Hasan

We consider super Yang-Mills theory and discuss how to extract the strong coupling limit of non-planar corrections to observables involving the -…

expansion of circular Wilson loop in superconformal quiver

Matteo Beccaria, Arkady A. Tseytlin

Localization approach to superconformal quiver theory leads to a non-Gaussian two-matrix model representation for the expectation value of BPS c…
