Algebraic Classification of Weyl Anomalies in Arbitrary Dimensions
Nicolas Boulanger
Conformally invariant massless field systems involving only dimensionless parameters are known to describe particle physics at very high energy. In the presence of an external grav…
General solutions of the Wess-Zumino consistency condition for the Weyl anomalies
Nicolas Boulanger
The general solutions of the Wess-Zumino consistency condition for the conformal (or Weyl, or trace) anomalies are derived. The solutions are obtained, in arbitrary dimensions, by…
Mixed symmetry gauge fields in a flat background
Xavier Bekaert, Nicolas Boulanger
We present a list of all inequivalent bosonic covariant free particle wave equations in a flat spacetime of arbitrary dimension. The wave functions are assumed to have a finite num…
No consistent cross-interactions for a collection of massless spin-2 fields
Nicolas Boulanger, Thibault Damour, Leonardo Gualtieri +1
We report a no-go theorem excluding consistent cross-couplings for a collection of massless, spin-2 fields described, in the free limit, by the sum of Pauli-Fierz actions (one for…
