1-form symmetry versus large N QCD
Journal of High Energy Physics, 2023 We show that large N QCD does not have an emergent ℤ N 1-form symmetry. Our results suggest that a symmetry-based understanding of (approximate) confinement in QCD would require some further generalization of the notion of generalized global symmetries.

Hamiltonian Approach to QCD in Coulomb Gauge: A Survey of Recent Results
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 We report on recent results obtained within the Hamiltonian approach to QCD in Coulomb gauge. Furthermore this approach is compared to recent lattice data, which were obtained by an alternative gauge‐fixing method and which show an improved agreement with the continuum results. By relating the Gribov confinement scenario to the center vortex picture of

Dreibein as Prepotential for Three‐Dimensional Yang‐Mills Theory
Advances in High Energy Physics, Volume 2017, Issue 1, 2017., 2017 We advocate and develop the use of the dreibein (and the metric) as prepotential for three‐dimensional SO(3) Yang‐Mills theory. Since the dreibein transforms homogeneously under gauge transformation, the metric is gauge invariant. For a generic gauge potential, there is a unique dreibein on fixing the boundary condition.

Quantization conditions and the double copy
Journal of High Energy Physics, 2022 We formulate Wilson loop observables as products of eikonal Wilson lines given in terms of on-shell scattering amplitudes. We derive the eikonal phases for dyons in both gauge theory and gravity, which we use to derive the Dirac-Schwinger-Zwanziger ...

Dyons, Superstrings, and Wormholes: Exact Solutions of the Non‐Abelian Dirac‐Born‐Infeld Action
Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015 We construct dyon solutions on coincident D4‐branes, obtained by applying T‐duality transformations to type I SO(32) superstring theory in 10 dimensions. These solutions, which are exact, are obtained from an action comprising the non‐Abelian Dirac‐Born‐Infeld action and a Wess‐Zumino‐like action. When one spatial dimension of the D4‐branes is taken to

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

International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012 We compute the phase and the modulus of an energy‐ and pressure‐free, composite, adjoint, and inert field ϕ in an SU(2) Yang‐Mills theory at large temperatures. This field is physically relevant in describing part of the ground‐state structure and the quasiparticle masses of excitations. The field ϕ possesses nontrivial S1‐winding on the group manifold

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

Holography at Work for Nuclear and Hadron Physics
Advances in High Energy Physics, Volume 2011, Issue 1, 2011., 2011 The purpose of this review is to provide basic ingredients of holographic QCD to nonexperts in string theory and to summarize its interesting achievements in nuclear and hadron physics. We focus on results from a less stringy bottom‐up approach and review a stringy top‐down model with some calculational details.

Precision holography for N=2∗ $$ \mathcal{N}={2}^{\ast } $$ on S 4 from type IIB supergravity
Journal of High Energy Physics, 2018 We find a new supersymmetric solution of type IIB supergravity which is holographically dual to the planar limit of the four-dimensional N=2∗ $$ \mathcal{N}={2}^{\ast } $$ supersymmetric Yang-Mills theory on S 4.
