Geometry in Scattering Amplitudes

Published 14 Oct 2022 in hep-ph and hep-th | (2210.08000v2)

Abstract: We formulate the field-space geometry for an effective field theory of scalars and gauge bosons. Geometric invariants such as the field-space curvature enter in both scattering amplitudes and the renormalization group equations, with the scalar and gauge results unified in a single expression.
