1. Conformal invariance versus Weyl invariance.

Author

Alvarez, Enrique, Anero, Jesus, and Santos-Garcia, Raquel

Subjects
*CONFORMAL invariants, *CONFORMAL mapping, *PARTICLE spin, *SPACETIME
Abstract

The most general Lagrangian describing spin 2 particles in flat spacetime and containing operators up to (mass) dimension 6 is carefully analyzed, determining the precise conditions for it to be invariant under linearized (transverse) diffeomorphisms, linearized Weyl rescalings, and conformal transformations.

Abstract

We have recently undergone an analysis of gravitational theories as defined in first order formalism, where the metric and the connection are treated as independent fields. The physical meaning of the connection field has historically been somewhat elusive. In this paper, a complete spin analysis of the torsionless connection field is performed, and its consequences are explored. The main properties of a hypothetical consistent truncation of the theory are discussed as well. [ABSTRACT FROM AUTHOR]
