Covariant approach to allowed beta decay
Sergio Cruz-Alzaga, Adam Falkowski
We propose a Lorentz-covariant on-shell formalism for allowed nuclear beta decay. Nuclear matrix elements are organized in a systematic effective field theory expansion in the reco…
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.…
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…
Modelling strong interactions and longitudinally polarized vector boson scattering
Adam Falkowski, Stefan Pokorski, J. P. Roberts
We study scattering of the electroweak gauge bosons in 5D warped models. Within two different models we determine the precise manner in which the Higgs boson and the vector resonan…
