On continuous 2-category symmetries and Yang-Mills theory

open access: yesJournal of High Energy Physics, 2022
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.

Precision matching of circular Wilson loops and strings in AdS 5 × S 5

open access: yesJournal of High Energy Physics, 2018
Previous attempts to match the exact N=4 $$ \mathcal{N}=4 $$ super Yang-Mills expression for the expectation value of the 12 $$ \frac{1}{2} $$-BPS circular Wilson loop with the semiclassical AdS 5 × S 5 string theory prediction were not successful at the

The next-to-next-to-leading order soft function for top quark pair production

open access: yesJournal of High Energy Physics, 2018
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.

Wilson loops and defect RG flows in ABJM

open access: yesJournal of High Energy Physics, 2023
We continue our study of renormalization group (RG) flows on Wilson loop defects in ABJM theory, which we have initiated in arXiv:2211.16501 . We generalize that analysis by including non-supersymmetric fixed points and RG trajectories.

Quark-antiquark potential in defect conformal field theory

open access: yesJournal of High Energy Physics, 2017
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

String corrections to circular Wilson loop and anomalies

open access: yesJournal 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

open access: yesJournal 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,

String tensions in deformed Yang-Mills theory

open access: yesJournal 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 $$ {\mathbb{R}}^3\times {\mathbb{S}}^1 $$.

Line operators in the Standard Model

open access: yesJournal 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.

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

open access: yesJournal 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.
