Extracting Einstein from the loop-level double-copy

A bstract The naive double-copy of (multi) loop amplitudes involving massive matter coupled to gauge theories will generically produce in a gravitational theory that contains additional contributions from propagating antisymmetric tensor and dilaton states even at tree-level. We present graph-based approach combines the method maximal cuts with construction offer systematic framework isolate pure Einstein-Hilbert through level. Indeed this allows for bootstrap pure-gravitational results scalar-QCD. apply construct novel result D -dimensional one-loop five-point QFT integrand relevant classical limit generating observables associated radiative effects black-hole scattering via gravity.
