Schwinger-Dyson = Wheeler-DeWitt: gauge theory observables as bulk operators

, 2000
We argue that the second-order gauge-invariant Schwinger-Dyson operator of a gauge theory is the Wheeler-DeWitt operator in the dual string theory.

The influence of Wilson lines on heavy quark anti-quark potential and mass

Journal of High Energy Physics
The holographic heavy quark potential is investigated via holographic Wilson loops in the AdS soliton with gauge potential. We analyze two types of holographic Wilson loops. In the first type, holographic heavy quark potential shows the area law behavior.

Jackiw-Nohl-Rebbi two-instanton as a source of magnetic monopole loop

, 2010
We demonstrate that a Jackiw-Nohl-Rebbi solution as the most general two-instanton generates a circular loop of magnetic monopole in four-dimensional Euclidean SU(2) Yang-Mills theory, in contrast to the one-instanton solution in the regular gauge for ...

On the stability of Dirac sheet configurations

, 2004
Using cooling for SU(2) lattice configurations, purely Abelian constant magnetic field configurations were left over after the annihilation of constituents that formed metastable Q=0 configurations.

Two-loop four-point amplitudes on the Coulomb branch of N $$ \mathcal{N} $$ = 4 super Yang-Mills

Journal of High Energy Physics
We explore scattering amplitudes on the Coulomb branch of maximally supersymmetric Yang-Mills theory. We introduce a particular pattern of scalar vacuum expectation values that allow us to define amplitudes with a different mass pattern compared to what ...

Wilson loops and wormholes

Journal of High Energy Physics
We analyse the properties of Wilson loop observables for holographic gauge theories, when the dual bulk geometries have a single and/or multiple boundaries (Euclidean spacetime wormholes).

A new method for calculating the soft anomalous dimension matrix for massive particle scattering

Journal of High Energy Physics
The general structure of infrared divergences in the scattering of massive particles is captured by the soft anomalous dimension matrix. The latter can be computed from a correlation function of multiple Wilson lines. The state-of-the-art two-loop result

A two-loop four-point form factor at function level

Journal of High Energy Physics
Recently, the maximally-helicity-violating four-point form factor for the chiral stress-energy tensor in planar N $$ \mathcal{N} $$ = 4 super Yang-Mills was computed to three loops at the level of the symbol associated with multiple polylogarithms.

Flat-space limit of defect correlators and stringy AdS form factors

Journal of High Energy Physics
We study AdS form factors, given by the Mellin representation for CFT correlators of local operators in the presence of extended defects. We propose a formula for taking (and expanding around) the flat-space limit.
