Derives expansion formulas for multi-trace YMS amplitudes bottom-up from soft gluon and scalar behaviors.
Hidden zeros in tree-level amplitudes of several theories are attributed to zeros of bi-adjoint scalar amplitudes via universal expansions, with a mechanism shown to cancel potential propagator divergences in gravity.
