چکیده
We study sources for torsion in Poincare gauge theory of any dimension, signature, and spin. find that symmetric kinetic terms non-Yang-Mills bosonic fields arbitrary rank drive torsion. Our detailed discussion spin-3/2 Rarita-Schwinger shows they source all independent parts the develop systematic notation spin-(2k+1)/2 spin tensor k n > 2k dimensions. For 0 there is a novel direct coupling between spinor fields. also cast well-known relation canonical Belinfante-Rosenfield energy tensors different choices variables.

Torsion formulation of gravity
We make it precise what it means to have a connection with torsion as solution of the Einstein equations. While locally the theory remains the same, the new formulation allows for topologies that would have been excluded in the standard formulation of gravity. In this formulation it is possible to couple arbitrary torsion to gauge fields without breaking the gauge invariance.
متن کاملNew Gauge Symmetry in Gravity and the Evanescent Role of Torsion
If the Einstein-Hilbert action LEH ∝ R is re-expressed in Riemann-Cartan spacetime using the gauge fields of translations, the vierbein field hμ, and the gauge field of local Lorentz transformations, the spin connection Aμα β , there exists a new gauge symmetry which permits reshuffling the torsion, partially or totally, into the Cartan curvature term of the Einstein tensor, and back, via a new...
متن کاملYang - Mills gauge anomalies in the presence of gravity with torsion
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 anomalie...
متن کاملGauge Theory of Gravity
The quantum gravity is formulated based on principle of local gauge invariance. The model discussed in this paper has local gravitational gauge symmetry and gravitational field appears as gauge field. The problems on quantization and renormalization of the theory are also discussed in this paper. In leading order approximation, the gravitational gauge field theory gives out classical Newton’s t...
متن کاملTorsion, Dilaton and Gauge Couplings
Non-Abelian gauge fields are traditionally not coupled to torsion due to violation of gauge invariance. However, it is possible to couple torsion to Yang-Mills fields while maintaining gauge invariance provided one accepts that the gauge couplings then become scalar fields. In the past this has been untenable from experimental constraints at the current epoch for the electromagnetic field at le...
