On parity-odd sector in metric-affine theories

HIGHLIGHTS

• who: Jose Beltru00e1n Jimu00e9nez and colleagues from the Departamento de Fu00edsica Fundamental and IUFFyM, Universidad de Salamanca, Salamanca, Spain have published the paper: On parity-odd sector in metric-affine theories, in the Journal: Eur. Phys. J. C
• what: The authors demonstrate that there are only 12 linearly independent scalars plus an additional one that can be removed by using the Pontryagin invariant. In this approach, the corresponding gauge field strength of the connection is identified with the curvature, in terms of which the authors can build a quadratic Lagrangian, as in Yang-Mills theory . . .
