On continuous 2-category symmetries and Yang-Mills theory
We study a 4d gauge theory U(1) N−1 ⋊ S N obtained from a U(1) N−1 theory by gauging a 0-form symmetry S N . We show that this theory has a global continuous 2-category symmetry, whose structure is particularly rich for N > 2.

The next-to-next-to-leading order soft function for top quark pair production
We present the first calculation of the next-to-next-to-leading order threshold soft function for top quark pair production at hadron colliders, with full velocity dependence of the massive top quarks.

ABSTRACT We propose a manifestly duality‐invariant, Lorentz‐invariant, and local action to describe quantum electrodynamics in the presence of magnetic monopoles that derives from Sen's formalism. By employing field strengths as the dynamical variables, rather than potentials, this formalism resolves longstanding ambiguities in prior frameworks.

Quark-antiquark potential in defect conformal field theory
We consider antiparallel Wilson lines in N $$ \mathcal{N} $$ = 4 super Yang-Mills in the presence of a codimension-1 defect. We compute the Wilson lines’ expectation value both at weak coupling, in the gauge theory, and at strong coupling, by finding the

We present a two-loop calculation of the supersymmetric circular Wilson loop in the N $$ \mathcal{N} $$ = 2* super Yang-Mills theory on the four-sphere. We develop an efficient framework for computing contributing Feynman graphs that relies on using the ...

Generic Axion Maxwell Equations: Path Integral Approach
It is possible that the interactions between axions and electromagnetic field are mediated by heavy dyons. In this article, the corresponding axion Maxwell equations are derived using the path integral approach. These equations feature novel axion‐dependent terms which can lead to unique signatures in light‐shining‐through‐wall and haloscope ...

String corrections to circular Wilson loop and anomalies
We study string quantum corrections to the ratio of latitude and circular Wilson loops in N $$ \mathcal{N} $$ = 4 super-Yang-Mills theory at strong coupling. Conformal gauge for the corresponding minimal surface in AdS5 × S 5 is singular and we show that

The instanton liquid and the axion [PDF]
The ultimate goal of this thesis is to improve our understanding of the cosmology of axions. Axions couple to QCD instantons and these non-perturbative effects are modeled within the framework of the interacting instanton liquid model (IILM).

Semi-Abelian gauge theories, non-invertible symmetries, and string tensions beyond N-ality
We study a 3d lattice gauge theory with gauge group U(1) N−1 ⋊ S N , which is obtained by gauging the S N global symmetry of a pure U(1) N−1 gauge theory, and we call it the semi-Abelian gauge theory.
