Exact partition functions for deformed $N = 2$ theories with $N_{f} = 4$ flavours

Matteo Beccaria, Alberto Fachechi, Guido Macorini +1

We consider the $Ω$ -deformed $N = 2$ $S U (2)$ gauge theory in four dimensions with $N_{f} = 4$ massive fundamental hypermultiplets. The low energy effective action depends on…

On triviality of S-matrix in conformal higher spin theory

M. Beccaria, S. Nakach, A. A. Tseytlin

We consider the conformal higher spin (CHS) theory in d=4 that contains the s=1 Maxwell vector, s=2 Weyl graviton and their higher spin s=3,4,... counterparts with higher-derivativ…

Exact partition functions for the $Ω$ -deformed $N = 2^{*}$ $S U (2)$ gauge theory

Matteo Beccaria, Guido Macorini

We study the low energy effective action of the $Ω$ -deformed $N = 2^{*}$ $S U (2)$ gauge theory. It depends on the deformation parameters $ε_{1}, ε_{2}$ , the scalar field exp…

On the large $Ω$ -deformations in the Nekrasov-Shatashvili limit of $N = 2^{*}$ SYM

Matteo Beccaria

We study the multi-instanton partition functions of the $Ω$ -deformed $N = 2^{*}$ $S U (2)$ gauge theory in the Nekrasov-Shatashvili (NS) limit. They depend on the deformatio…

On the cusp anomalous dimension in the ladder limit of $N = 4$ SYM

Matteo Beccaria, Alberto Fachechi, Guido Macorini

We analyze the cusp anomalous dimension in the (leading) ladder limit of $N = 4$ SYM and present new results for its higher-order perturbative expansion. We study two differ…

The ground state of long-range Schrodinger equations and static $q q ˉ$ potential

Matteo Beccaria, Giorgio Metafune, Diego Pallara

Motivated by the recent results in arXiv:1601.05679 about the quark-antiquark potential in $N = 4$ SYM, we reconsider the problem of computing the asymptotic weak-coupling e…
