Effective action of dilaton gravity as the classical double copy of Yang-Mills theory
Jan Plefka, Jan Steinhoff, Wadim Wormsbecher
We compute the classical effective action of color charges moving along worldlines by integrating out the Yang-Mills gauge field to next-to-leading order in the coupling. An adapte…
New relations for graviton-matter amplitudes
Jan Plefka, Wadim Wormsbecher
We present new relations for scattering amplitudes of color ordered gluons, massive quarks and scalars minimally coupled to gravity. Tree-level amplitudes of arbitrary matter and g…
Collinear limits beyond the leading order from the scattering equations
Dhritiman Nandan, Jan Plefka, Wadim Wormsbecher
The structure of tree-level scattering amplitudes for collinear massless bosons is studied beyond their leading splitting function behavior. These near-collinear limits at sub-lead…
Spontaneously broken conformal invariance in observables
Rutger H. Boels, Wadim Wormsbecher
Conformal invariance is spontaneously broken in many physical systems leading to the appearance of a single massless Goldstone mode in the spectrum, the dilaton. The dilaton soft l…
