A Basis for Invariants in Non–abelian Gauge Theories
نویسنده
چکیده
An algorithm is described to convert Lorentz and gauge invariant expressions in non– Abelian gauge theories with matter into a standard form, consisting of a linear combination of basis invariants. This algorithm is needed for computer calculations of effective actions. The defining properties of the basis invariants are reported. The number of basis invariants up to mass dimension 16 are presented.

Basis Invariants in Non–Abelian Gauge Theories
A basis of Lorentz and gauge-invariant monomials in non-Abelian gauge theories with matter is described, applicable for the inverse mass expansion of effective actions. An algorithm to convert a arbitrarily given invariant expression into a linear combination of the basis elements is presented. The linear independence of the basis invariants is proven.
متن کاملGauge Properties of Conserved Currents in Abelian Versus Nonabelian Theories
We clarify the physical origin of the difference between gauge properties of conserved currents in abelian and nonabelian theories. In the latter, but not in the former, such currents can always be written on shell as gauge invariants modulo identically conserved, superpotential, terms. For the “isotopic” vector and the stress tensor currents of spins 1 and 2 respectively, we explain this diffe...
متن کاملSuper-Pohlmeyer invariants and boundary states for non-abelian gauge fields
Aspects of the supersymmetric extension of the Pohlmeyer invariants are studied, and their relation to superstring boundary states for non-abelian gauge fields is discussed. We show that acting with a super-Pohlmeyer invariant with respect to some non-abelian gauge field A on the boundary state of a bare D9 brane produces the boundary state describing that non-abelian background gauge field on ...
متن کاملRepresentations of Composite Braids and Invariants for Mutant Knots and Links in Chern - Simons Field Theories
We show that any of the new knot invariants obtained from Chern-Simons theory based on an arbitrary non-abelian gauge group do not distinguish isotopically inequivalent mutant knots and links. In an attempt to distinguish these knots and links, we study Murakami (symmetrized version) r-strand composite braids. Salient features of the theory of such composite braids are presented. Representation...
متن کاملThe Geometry of Supersymmetric Gauge Theories in Four Dimensions
We review the relations between (twisted) supersymmetric gauge theories in four dimensions and moduli problems in four-dimensional topology, and we study in detail the non-abelian monopole equations from this point of view. The relevance of exact results in N = 1 and N = 2 supersymmetric gauge theories to the computation of topological invariants is emphasized. Some background material is provi...
