Wavy Wilson Line and AdS/CFT [PDF]

, 2004
Wilson loops which are small deviations from straight, infinite lines, called wavy lines, are considered in the context of the AdS/CFT correspondence. A single wavy line and the connected correlation function of a straight and wavy line are considered ...

SO(3) versus SU(2) lattice gauge theory

, 2002
We consider the SO(3) lattice gauge theory at weak coupling, in the Villain action. We exhibit an analytic path in coupling space showing the equivalence of the SO(3) theory with SU(2) summed over all twist sectors. This clarifies the ``mysterious phase''

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.

Phases of Wilson lines: conformality and screening

Journal of High Energy Physics, 2023
We study the rich dynamics resulting from introducing static charged particles (Wilson lines) in 2+1 and 3+1 dimensional gauge theories. Depending on the charges of the external particles, there may be multiple defect fixed points with interesting ...

Thermal N = 4 SYM theory as a 2D Coulomb gas

, 2006
We consider N = 4 supersymmetric Yang-Mills theory with SU(N) gauge group at large N and at finite temperature on a spatial S^3. We show that, at finite weak 't Hooft coupling, the theory is naturally described as a two dimensional Coulomb gas of complex

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.

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.

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 ...

On renormalons of static QCD potential at u = 1/2 and 3/2

Journal of High Energy Physics, 2020
We investigate the u = 1 / 2 O Λ QCD $$ u=1/2\left[\mathcal{O}\left({\Lambda}_{\mathrm{QCD}}\right)\right] $$ and u = 3 / 2 O Λ QCD 3 $$ u=3/2\left[\mathcal{O}\left({\Lambda}_{\mathrm{QCD}}^3\right)\right] $$ renormalons in the static QCD potential in ...
