Covariant field theory for self-dual strings
(1997-11-10)
We give a gauge and manifestly SO(2,2) covariant formulation of the field theory of the self-dual string. The string fields are gauge connections that turn the super-Virasoro generators into covariant derivatives, © 1997 ...
On the coupling of the self-dual field to dynamical U(1) matter and its dual theory
(Iop Publishing Ltd, 2004-02-13)
We consider arbitrary U (1) charged matter non-minimally coupled to the self-dual field in d = 2 + 1. The coupling includes a linear and a rather general quadratic term in the self-dual field. By using both Lagragian gauge ...
Quantum equivalence between the self-dual and the Maxwell-Chern-Simons models nonlinearly coupled to U(1) scalar fields
(Iop Publishing Ltd, 2006-07-21)
The use of master actions to prove duality at quantum level becomes cumbersome if one of the dual fields interacts nonlinearly with other fields. This is the case of the theory considered here consisting of U(1) scalar ...
Class of self-dual models in three dimensions
(2000-01-15)
In the present paper we introduce a hierarchical class of self-dual models in three dimensions, inspired in the original self-dual theory of Towsend-Pilch-Nieuwenhuizen. The basic strategy is to explore the powerful property ...
A new spin-2 self-dual model in D=2+1
(Int School Advanced Studies, 2009-09-01)
There are three self-dual models of massive particles of helicity + 2 (or -2) in D = 2 + 1. Each model is of first, second, and third-order in derivatives. Here we derive a new self-dual model of fourth-order, L(SD)((4)), ...
Self-dual super-Yang-Mills as a string theory in (x, 0) space
(Int School Advanced Studies, 2004-05-01)
Different string theories in twistor space have recently been proposed for describing N = 4 super-Yang-Mills. In this paper, a string theory in (x, theta) space is constructed for self-dual N = 4 super-Yang-Mills. It is ...
Manifestly covariant actions for D=4 self-dual Yang-Mills and D=10 super-Yang-Mills
(Editrice Compositori Bologna, 1998-02-01)
Using an infinite number of fields, we construct actions for D = 4 self-dual Yang-Mills with manifest Lorentz invariance and for D = 10 super-Yang-Mills with manifest super-Poincare invariance. These actions are generalizations ...

Different string theories in twistor space have recently been proposed for describing N = 4 super-Yang-Mills. In this paper, a string theory in (x, θ) space is constructed for self-dual N = 4 super-Yang-Mills. It is hoped ...
Manifestly covariant actions for D = 4 self-dual Yang-Mills and D = 10 super-Yang-Mills
(1998-12-01)
Using an infinite number of fields, we construct actions for D = 4 self-dual Yang-Mills with manifest Lorentz invariance and for D = 10 super-Yang-Mills with manifest super-Poincaré invariance. These actions are generalizations ...
Duality between non-commutative Yang-Mills-Chem-Simons and non-Abelian self-dual models
(Elsevier B.V., 2003-04-03)
By introducing an appropriate parent action and considering a perturbative approach, we establish, up to fourth order terms in the field and for the full range of the coupling constant, the equivalence between the ...
