Gauge anomalies on shell and collinear factorization
Edoardo Alviani, Adam Falkowski
We revisit gauge anomalies from the purely on-shell perspective. We argue that violation of anomaly cancellation conditions manifests as a breakdown of collinear factorization. We…
UV completions of scalar-tensor EFTs
Edoardo Alviani, Adam Falkowski, Panagiotis Marinellis
We study models that give rise to scalar-tensor effective field theories (EFTs) at low energies. Our framework involves massive particles of spin coupled to gravity a…
Matching and positivity beyond minimal coupling
Edoardo Alviani, Adam Falkowski
We study the low-energy effective theories of photons and gravitons, matching them at one loop to a UV completion with a massive spinning matter particle. The matter is allowed to…
Spinning waveforms of scalar radiation in quadratic modified gravity
Adam Falkowski, Panagiotis Marinellis
We study scalar-tensor gravitational theories using on-shell amplitude methods. We focus on theories with gravity coupled to a massless scalar via the Gauss-Bonnet and Chern-Simons…
