New duality transformation in two-dimensional non-linear sigma models
نویسنده
چکیده
A new T-duality transformation is found in two-dimensional non-linear sigma models. This is a straightforward generalisation of Abelian and non-Abelian T-dualities. It is shown, in particular, that a given non-linear sigma model can possess more than one dual theory. Finally, the construction of this duality is given a geometrical interpretation. e-mail: [email protected] CNRS UMR 6083

Gauged Heterotic Sigma-models
The gauging of isometries in general sigma-models which include fermionic terms which represent the interaction of strings with background Yang-Mills fields is considered. Gauging is possible only if certain obstructions are absent. The quantum gauge anomaly is discussed, and the (1,0) supersymmetric generalisation of the gauged action given. Non-linear sigma-models are important two-dimensiona...
متن کاملOn the geometry of classically integrable two-dimensional non-linear sigma models
A master equation expressing the classical integrability of two-dimensional non-linear sigma models is found. The geometrical properties of this equation are outlined. In particular, a closer connection between integrability and T-duality transformations is emphasised. Finally, a whole new class of integrable non-linear sigma models is found and all their corresponding Lax pairs depend on a spe...
متن کاملOn Quantum Equivalence of Dual Sigma Models: Sl(3) Examples
The equivalence of several SL(3) sigma models and their special Abelian duals is investigated in the two loop order of perturbation theory. The investigation is based on extracting and comparing various β functions of the original and dual models. The role of the discrete global symmetries is emphasized. 1 1. Introduction Various target space duality transformations [1-3] ('T duality') connecti...
متن کاملPseudoduality in Sigma Models
We revisit classical “on shell” duality, i.e., pseudoduality, in two dimensional conformally invariant classical sigma models and find some new interesting results. We show that any two sigma models that are “on shell” duals have opposite 1-loop renormalization group beta functions because of the integrability conditions for the pseudoduality transformation. A new result states for any two comp...
متن کاملN = (4, 4) Supersymmetry and T-Duality
A sigma model with four-dimensional target space parametrized by chiral and twisted chiral N =(2, 2) superfields can be extended to N =(4, 4) supersymmetry off-shell, but this is not true for a model of semichiral fields, where the N = (4, 4) supersymmetry can only be realized on-shell. The two models can be related to each other by T-duality. In this paper we perform a duality transformation f...
