Kummitus: a light-weight toolbox for counting DOF in perturbative QFT

Carlo Marzo

The consistent construction of quantum field theories beyond the simplest cases requires a precise characterization of the propagating degrees of freedom. These are encoded in the…

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…

PSALTer: Particle Spectrum for Any Tensor Lagrangian

Will Barker, Carlo Marzo, Claire Rigouzzo

We present the PSALTer software for efficiently computing the mass and energy of the particle spectrum for any (e.g. higher-rank) tensor field theory in the Wolfram Language. The u…
