Higher spin Lagrangians from higher derivative diffeomorphisms
Will Barker, Dario Francia, Carlo Marzo +1
The covariant description of massless particles of arbitrary spin typically employs symmetric tensors of rank and rests on a local symmetry carried by symmetric tensor paramete…
Infrared foundations for quantum geometry II: Catalogue of all torsion-like theories including new ghost-tachyon-free cases
Will Barker, Carlo Marzo, Alessandro Santoni
The construction of consistent effective field theories in the infrared demands that models be defined by their underlying gauge symmetries, rather than by an arbitrary tuning of c…
Infrared foundations for quantum geometry I: Catalogue of totally symmetric rank-three field theories
Will Barker, Carlo Marzo, Alessandro Santoni
We systematically obtain all linear models which propagate a totally symmetric rank-three field without parity violation on a flat background. Each such model is defined exclusivel…
Can metric-affine gravity be saved?
Will Barker, Carlo Marzo, Alessandro Santoni
Like general relativity, metric-affine gravity should be a viable effective quantum theory, otherwise it is a mathematical curiosity without physical application. Assuming a pertur…
