Large N QCD -- Continuum reduction

, 2003
Numerical evidence combined with Eguchi-Kawai reduction indicate that there are no finite volumes effects in the large N limit of QCD as long as the linear extent of the four-torus is bigger than a critical size.

Casimir scaling and renormalization of Polyakov loops in large-N gauge theories [PDF]

, 2012
We study Casimir scaling and renormalization properties of Polyakov loops in different irreducible representations in SU(N) gauge theories; in particular, we investigate the approach to the large-N limit, by performing lattice simulations of Yang-Mills ...

One-dimensional QCD at finite density and its ’t Hooft-Veneziano limit

Journal of High Energy Physics
An exact solution of one-dimensional lattice gauge theory at finite temperature and non-zero chemical potential is reviewed for the gauge groups G = Z(N), U(N), SU(N) for all values of N and the number of fermion flavors Nf.

Ironing out the crease

Journal of High Energy Physics, 2022
The crease is a surface operator folded by a finite angle along an infinite line. Several realisations of it in the 6d N $$ \mathcal{N} $$ = (2, 0) theory are studied here. It plays a role similar to the generalised quark-antiquark potential, or the cusp

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

Journal of High Energy Physics, 2020
We compute the planar limit of both the free energy and the expectation value of the 1/2 BPS wilson loop for four dimensional N $$ \mathcal{N} $$ = 2 superconformal quiver theories, with a product of SU(N)s as gauge group and hi-fundamental matter ...

Center vortices of Yang-Mills theory at finite temperatures

, 1999
Recent lattice calculations performed at zero temperature and in the maximal center gauge indicate that quark confinement can be understood in this gauge as due to fluctuations in the number of magnetic vortices piercing a given Wilson loop.

Why the Quark-Gluon Plasma isn't a Plasma [PDF]

, 2001
An alternate picture of the deconfined phase of gauge theories is described. Instead of a plasma, the theory is viewed as a condensate of Polyakov lines.

Interpolating Wilson loops and enriched RG flows

Journal of High Energy Physics, 2023
We study new 1/24 BPS circular Wilson loops in ABJ(M) theory, which are defined in terms of several parameters that continuously interpolate between previously known 1/6 BPS loops (both bosonic and fermionic) and 1/2 BPS fermionic loops.

Exact $$ \mathcal{N} $$ = 2* Schur line defect correlators

Journal of High Energy Physics, 2023
We study the Schur line defect correlation functions in $$ \mathcal{N} $$ = 4 and $$ \mathcal{N} $$ = 2∗ U(N) super Yang-Mills (SYM) theory. We find exact closed-form formulae of the correlation functions of the Wilson line operators in the fundamental ...
