SU (N) gauge theories at large N

B Lucini, M Panero - Physics Reports, 2013 - Elsevier
We review the theoretical developments and conceptual advances that stemmed from the
generalization of QCD to the limit of a large number of color charges, originally proposed by't …

Echoes of a hidden valley at hadron colliders

MJ Strassler, KM Zurek - Physics Letters B, 2007 - Elsevier
We consider examples of “hidden-valley” models, in which a new confining gauge group is
added to the standard model. Such models often arise in string constructions, and …

New Nonperturbative Methods in Quantum Field Theory: From Large-N Orbifold Equivalence to Bions and Resurgence

GV Dunne, M Ünsal - Annual Review of Nuclear and Particle …, 2016 - annualreviews.org
We present a broad conceptual introduction to some new ideas in nonperturbative quantum
field theory (QFT) that have led to progress toward an understanding of quark confinement in …

Light composite Higgs boson from higher representations versus electroweak precision measurements: predictions for CERN LHC

DD Dietrich, F Sannino, K Tuominen - Physical Review D—Particles, Fields …, 2005 - APS
We investigate theories in which the technifermions in higher dimensional representations of
the technicolor gauge group dynamically break the electroweak symmetry of the standard …

Center-stabilized Yang-Mills theory: Confinement and large volume independence

M Ünsal, LG Yaffe - Physical Review D—Particles, Fields, Gravitation, and …, 2008 - APS
We examine a double trace deformation of SU (N) Yang-Mills theory which, for large N and
large volume, is equivalent to unmodified Yang-Mills theory up to O (1/N 2) corrections. In …

Volume independence in large Nc QCD-like gauge theories

P Kovtun, M Ünsal, LG Yaffe - Journal of High Energy Physics, 2007 - iopscience.iop.org
Volume independence in large N c gauge theories may be viewed as a generalized orbifold
equivalence. The reduction to zero volume (or Eguchi-Kawai reduction) is a special case of …

Vacuum structure of bifundamental gauge theories at finite topological angles

Y Tanizaki, Y Kikuchi - Journal of High Energy Physics, 2017 - Springer
A bstract We discuss possible vacuum structures of SU (n)× SU (n) gauge theories with
bifundamental matters at finite θ angles. In order to give a precise constraint, a mixed't Hooft …

Semiclassics with't Hooft flux background for QCD with 2-index quarks

Y Tanizaki, M Ünsal - Journal of High Energy Physics, 2022 - Springer
A bstract We study quantum chromodynamics including the two-index symmetric or anti-
symmetric quark (QCD (Sym/ASym)) on small ℝ 2× T 2 with a suitable magnetic flux. We first …

QCD-like theories on : A smooth journey from small to large <?format ?>with double-trace deformations

M Shifman, M Uensal - Physical Review D—Particles, Fields, Gravitation, and …, 2008 - APS
We consider QCD-like theories with one massless fermion in various representations of the
gauge group SU (N). The theories are formulated on R 3× S 1. In the decompactification limit …

IIB duals of D = 3 circular quivers
