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…

On the Coulomb corrections in nuclear beta decay
Edoardo Alviani, Adam Falkowski
We propose a Lorentz invariant and little group covariant description of beta decay amplitudes relying on on-shell amplitude methods and the spinor variables for massive particles.…
