چکیده

We study aspects of the large-N volume independence on R×L, where L is a Γ-site lattice for Yang-Mills theory with adjoint Wilson-fermions. We find the critical number of lattice sites above which the center-symmetry analysis on L agrees with the one on the continuum S. For Wilson parameter set to one and Γ≥2, the two analyses agree. One-loop radiative corrections to Wilson-line masses are finite, reminiscent of the UV-insensitivity of the Higgs mass in deconstruction/Little-Higgs theories. Even for theories with Γ=1, volume independence in QCD(adj) may be guaranteed to work by tuning one low-energy effective field theory parameter. Within the parameter space of the theory, at most three operators of the 3d effective field theory exhibit one-loop UV-sensitivity. This opens the analytical prospect to study 4d non-perturbative physics by using lower dimensional field theories (d=3, in our example). ∗[email protected][email protected]

Center-stabilized Yang-Mills theory: confinement and large N volume independence

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/N2) corrections. In contrast to the unmodified theory, large N volume independence is valid in the deformed theory down to arbitrarily small volumes. The double trace deformation prevents the spontaneous breaking of center symmetry which w...

Large-N volume independence in conformal and confining gauge theories

Consequences of large N volume independence are examined in conformal and confining gauge theories. In the large N limit, gauge theories compactified on Rd−k × (S) are independent of the S radii, provided the theory has unbroken center symmetry. In particular, this implies that a large N gauge theory which, on R, flows to an IR fixed point, retains the infinite correlation length and other scal...

Volume independence in large Nc QCD-like gauge theories

Volume independence in large Nc gauge theories may be viewed as a generalized orbifold equivalence. The reduction to zero volume (or Eguchi-Kawai reduction) is a special case of this equivalence. So is temperature independence in confining phases. A natural generalization concerns volume independence in “theory space” of quiver gauge theories. In pure Yang-Mills theory, the failure of volume in...

It has been proposed that four-dimensional QCD with fermions in the adjoint representation exhibits volume-independence in the large-N limit. If correct, this would mean that results for physical quantities could be obtained from the single-site version of the model. A necessary condition for volume-independence is that the (ZN) center-symmetry of the single-site theory is unbroken. We explore ...

Large N Volume Independence and an Emergent Fermionic Symmetry

Large-N volume independence in circle-compactified QCD with adjoint Weyl fermions implies the absence of any phase transitions as the radius is dialed to arbitrarily small values. This class of theories are believed to possess a Hagedorn density of hadronic states. It turns out that these properties are in apparent tension with each other, because a Hagedorn density of states typically implies ...
