Localization and resummation of unstable instantons in 2d Yang-Mills
Luca Griguolo, Rodolfo Panerai, Jacopo Papalini +2
We compute the exact all-orders perturbative expansion for the partition function of 2d Yang-Mills theory on closed surfaces around higher critical points. We demo…
Supersymmetric localization of (higher-spin) JT gravity: a bulk perspective
Luca Griguolo, Luigi Guerrini, Rodolfo Panerai +2
We study two-dimensional Jackiw-Teitelboim gravity on the disk topology by using a BF gauge theory in the presence of a boundary term. The system can be equivalently written in a s…
The phase diagram of -deformed Yang-Mills theory on the sphere
Luca Griguolo, Rodolfo Panerai, Jacopo Papalini +1
We study the large- dynamics of -deformed two-dimensional Yang-Mills theory at genus zero. The 1/-expansion of the free energy is obtained by exploiting the associa…
Exact -deformation of two-dimensional Yang-Mills theory on the sphere
Luca Griguolo, Rodolfo Panerai, Jacopo Papalini +1
We study the deformation of two-dimensional Yang-Mills theory at genus zero by carrying out the analysis at the level of its instanton representation. We first focus on…
Exact deformation of two-dimensional Maxwell theory
Luca Griguolo, Rodolfo Panerai, Jacopo Papalini +1
-deformed two-dimensional quantum Maxwell theory on the torus is examined, taking into account nonperturbative effects in the deformation parameter . We study the…
Nonperturbative effects and resurgence in JT gravity at finite cutoff
Luca Griguolo, Rodolfo Panerai, Jacopo Papalini +1
We investigate the nonperturbative structure of Jackiw-Teitelboim gravity at finite cutoff, as given by its proposed formulation in terms of a -deformed Schwarzian quantu…
Topological Correlators and Surface Defects from Equivariant Cohomology
Rodolfo Panerai, Antonio Pittelli, Konstantina Polydorou
We find a one-dimensional protected subsector of matter theories on a general class of three-dimensional manifolds. By means of equivariant localization, we identif…
Form factor recursion relations at loop level
Lorenzo Bianchi, Andreas Brandhuber, Rodolfo Panerai +1
We introduce a prescription to define form factor integrands at loop level in planar supersymmetric Yang-Mills theory. This relies on a periodic kinematic configura…
Dual conformal invariance for form factors
Lorenzo Bianchi, Andreas Brandhuber, Rodolfo Panerai +1
Form factors of the stress-tensor multiplet operator in supersymmetric Yang-Mills reveal surprisingly simple structures similar to those appearing in scattering amp…
Supersymmetric Wilson loops in two dimensions and duality
Rodolfo Panerai, Matteo Poggi, Domenico Seminara
We classify bosonic supersymmetric Wilson loops on arbitrary backgrounds with vector-like R-symmetry. These can be defined on any smooth contour and come in two…
Deconstructing Little Strings with Gauge Theories on Ellipsoids
Joseph Hayling, Rodolfo Panerai, Constantinos Papageorgakis
A formula was recently proposed for the perturbative partition function of certain gauge theories on the round four-sphere, using an analytic-continuation argument i…
The connected prescription for form factors in twistor space
Andreas Brandhuber, Edward Hughes, Rodolfo Panerai +2
We propose a connected prescription formula in twistor space for all tree-level form factors of the stress tensor multiplet operator in super Yang-Mills, which is a…
