Yang - Mills gauge anomalies in the presence of gravity with torsion
نویسنده
چکیده
The BRST transformations for the Yang-Mills gauge fields in the presence of gravity with torsion are discussed by using the so-called Maurer-Cartan horizontality conditions. With the help of an operator δ which allows to decompose the exterior spacetime derivative as a BRST commutator we solve the Wess-Zumino consistency condition corresponding to invariant Chern-Simons terms and gauge anomalies.

Two-Dimensional Gravity and Nonlinear Gauge Theory
We construct a gauge theory based on nonlinear Lie algebras, which is an extension of the usual gauge theory based on Lie algebras. It is a new approach to generalization of the gauge theory. The two-dimensional gravity is derived from nonlinear Poincaré algebra, which is the new Yang-Mills like formulation of the gravitational theory. As typical examples, we investigate R2 gravity with dynamic...

It is shown that the SU (2) Yang-Mills theory in 3-dimensional Riemann-Cartan space-time can be completely reformulated as a gravity-like theory in terms of gauge invariant variables. The resulting Yang-Mills induced equations are found, and it is demonstrated that they can be derived from a torsion-square type of action.
متن کاملBRST cohomology of Yang-Mills gauge fields in the presence of gravity in Ashtekar variables
The BRST transformations for the Yang-Mills gauge fields in the presence of gravity described by Ashtekar variables are obtained by using the so-called Maurer-Cartan horizontality conditions. The BRST cohomology group expressed by the Wess-Zumino consistency condition is solved with the help of an operator δ introduced by S.P. Sorella which in our case has a very simple form and generates, toge...
متن کاملGeneral relativity reformed to a genuine Yang-Mills gauge theory for gravity
The theory of general relativity is reformed to a genuine Yang-Mills gauge theory of the Poincaré group for gravity. Several pathologies of the conventional theory are thus removed, but not every GR vacuum satisfies the Y-M equations. The sector of GR solutions which survive is fully classified and it is found to include the Schwarzschild black hole. Two other solutions presented here have no G...
متن کاملPost-Riemannian Merger of Weyl and/or Yang-Mills Interactions with Gravity
We show that a spacetime with torsion and non-metricity, obtained as a deformation of a Riemannian spacetime, accommodates an internal symmetry structure of the YangMills prototype in such a way that the internal symmetry becomes an integral part of the spacetime itself. In particular, the spacetime structural identities, which become “contaminated” by internal degrees of freedom, remain invari...
