Einstein Yang-Mills amplitudes from intersections of twisted forms

Abstract We present a geometric derivation of all-multiplicity (single-trace) tree-level Einstein Yang-Mills (EYM) amplitudes A $$ \mathcal{A} $$ (n; r) involving n gluons and r gravitons by a bilinear of two twisted differential forms on the moduli space of Riemann spheres with m := n + r punctures...
