Holographic ρ mesons in an external magnetic field

N Callebaut, D Dudal, H Verschelde - Journal of High Energy Physics, 2013 - Springer
A bstract We study the ρ meson in a uniform magnetic field eB using a holographic QCD-
model, more specifically a\(\mathrm {D} 4/\mathrm {D} 8/\overline {\mathrm {D} 8}\) brane …

Background effective action with nonlinear massive gauge fixing

H Gies, D Gkiatas, L Zambelli - Physical Review D, 2022 - APS
We combine a recent construction of a Becchi-Rouet-Stora-Tyutin (BRST)-invariant,
nonlinear massive gauge fixing with the background field formalism. The resulting …

Color confinement and color singlet structure of quantum states in Yang-Mills theory

DG Pak, RG Cai, T Tsukioka, P Zhang… - arXiv preprint arXiv …, 2020 - arxiv.org
We consider two fundamental long-standing problems in quantum chromodynamics (QCD):
the origin of color confinement and structure of a true vacuum and color singlet quantum …

Towards a BRST-invariant construction of pure Yang-Mills theory

D Gkiatas - 2023 - db-thueringen.de
In this thesis, we concentrate on the sector of QCD that does not include quarks, ie pure
Yang-Mills, for which we investigate different BRST-invariant realizations in perturbative and …

Gauge dynamics and topological insulators

B Béri, D Tong, K Wong - Journal of High Energy Physics, 2013 - Springer
A bstract A non-abelian magnetic field in Yang-Mills theory induces the formation of a “W-
boson” vortex lattice. We study the propagation of fundamental fermions in the presence of …

as a model of infinite-dimensional constant gauge field configurations

LCL Botelho - International Journal of Modern Physics A, 2017 - World Scientific
We study and clarify in a reduced dynamical model for QCD (SU (∞)) called Bollini–
Giambiagi model and defined by constant gauge fields Yang–Mills path integral several …

[PDF][PDF] Chiral superfluidity for QCD

T Kalaydzhyan - arXiv preprint arXiv:1412.0536, 2014 - researchgate.net
We argue that the strongly coupled quark-gluon plasma formed at LHC and RHIC can be
considered as a chiral superfluid. The “normal” component of the fluid is the thermalized …

Microscopic vacuum structure in a pure QCD

DG Pak, PM Zhang - arXiv preprint arXiv:1803.11027, 2018 - arxiv.org
We propose a class of stationary color magnetic solutions in a pure quantum
chromodynamics (QCD) which are stable under gluon quantum fluctuations. This resolves a …

Axially-symmetric stationary solutions in a pure SU (3) QCD

DG Pak, PM Zhang - arXiv preprint arXiv:1801.02392, 2018 - arxiv.org
We propose an ansatz for a class of regular axially-symmetric solutions in SU (3) QCD. After
averaging over time period the solution can be treated as a non-topological monopole …
