Title: Scaling function in AdS/CFT from the O(6) sigma model

Author: ; ; ; ;

Date: 2009

Submitted: 2020-08-11

(2009)

Asymptotic behavior of the anomalous dimensions of Wilson
operators with high spin and twist is governed in planar N = 4
SYM theory by the scaling, function which coincides at strong
coupling with the energy density of ...

Title: The puzzle of apparent linear lattice artifacts in the 2d non-linear sigma-model and Symanzik's solution

Author: ; ;

Date: 2010

Submitted: 2020-08-11

(2010)

Lattice artifacts in the 2d O(n) non-linear sigma-model are
expected to be of the form O(a(2)), and hence it was (when first
observed) disturbing that some quantities in the O(3) model with
various actions show ...

Title: Logarithmic corrections to O(a(2)) lattice artifacts

(2009)

We compute logarithmic corrections to the O(a(2)) lattice artifacts for a class of lattice actions for the non-linear O(n) sigma-model in two dimensions. The generic leading artifacts are of the form a(2)vertical bar ...

Author: ; ; ;

Date: 1994

Submitted: 2020-08-07

(1994)

Local Lagrangians are derived for a class of SU(2) invariant sigma models admitting two commuting Kac-Moody algebras at the level of Poisson brackets. The one-loop renormalizability of these models is established. Some ...

Title: Perturbative quantum (in)equivalence of dual σ models in two dimensions

Author: ; ; ;

Date: 1996

Submitted: 2020-08-07

(1996)

Various examples of target space duality transformations are investigated up to two loop order in perturbation theory. Our results show that when using the tree level ('naive') transformation rules the dual theories are ...

Title: Coadjoint orbits of the Virasoro algebra and the global Liouville equation

Author: ; ;

Date: 1998

Submitted: 2020-08-07

(1998)

The classification of the coadjoint orbits of the Virasoro
algebra is reviewed and then applied to analyze the so-called
global Liouville equation. The review is self-contained,
elementary and is tailor-made for the ...

Title: Quantum equivalence of sigma models related by non-Abelian duality transformations

Author: ; ; ; ; ;

Date: 1998

Submitted: 2020-08-07

(1998)

Coupling constant renormalization is investigated in two dimensional σ models related by non-Abelian duality transformations. In this respect it is shown that in the one loop order of perturbation theory the duals of a one ...

(1998)

The problem of quantum equivalence between non-linear sigma models related by Abelian or non-Abelian T-duality is studied in perturbation theory. Using the anomalous Ward identity for Weyl symmetry we derive a relation ...

(1996)

A modification of the Abelian duality transformations is proposed guaranteeing that a (not necessarily conformally invariant) sigma-model be quantum equivalent (at least up to two loops in perturbation theory) to its dual. ...
