String corrections to circular Wilson loop and anomalies

Journal of High Energy Physics, 2018
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

Study of gapped phases of 4d gauge theories using temporal gauging of the ℤ N 1-form symmetry

Journal of High Energy Physics, 2023
To study gapped phases of 4d gauge theories, we introduce the temporal gauging of ℤ N 1-form symmetry in 4d quantum field theories (QFTs), thereby defining effective 3d QFTs with ℤ ~ $$ \overset{\sim }{\mathbb{Z}} $$ N × ℤ N 1-form symmetry. In this way,

The planar limit of N $$ \mathcal{N} $$ = 2 superconformal field theories

Journal of High Energy Physics, 2020
We obtain the perturbative expansion of the free energy on S 4 for four dimensional Lagrangian N $$ \mathcal{N} $$ = 2 superconformal field theories, to all orders in the ’t Hooft coupling, in the planar limit.

String tensions in deformed Yang-Mills theory

Journal of High Energy Physics, 2018
We study k-strings in deformed Yang-Mills (dYM) with SU(N) gauge group in the semiclassically calculable regime on ℝ3×S1 $$ {\mathbb{R}}^3\times {\mathbb{S}}^1 $$.

Circular Wilson loop in N $$ \mathcal{N} $$ = 2* super Yang-Mills theory at two loops and localization

Journal of High Energy Physics, 2021
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 ...

Line operators in the Standard Model

Journal of High Energy Physics, 2017
There is an ambiguity in the gauge group of the Standard Model. The group is G = SU(3) × SU(2) × U(1)/Γ, where Γ is a subgroup of Z 6 which cannot be determined by current experiments.

Semi-Abelian gauge theories, non-invertible symmetries, and string tensions beyond N-ality

Journal of High Energy Physics, 2021
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.

Probing the dynamics of stringy flux tubes with large R-charge

Journal of High Energy Physics
We study the generalized cusp anomalous dimension, or quark-antiquark potential on the three-sphere, in the presence of a large R-charge L and at strong coupling.

A path integral formulation for particle detectors: the Unruh-DeWitt model as a line defect

Journal of High Energy Physics, 2021
Particle detectors are an ubiquitous tool for probing quantum fields in the context of relativistic quantum information (RQI). We formulate the Unruh-DeWitt (UDW) particle detector model in terms of the path integral formalism. The formulation is able to
