Syzygies Probing Scattering Amplitudes
Gang Chen, Junyu Liu, Ruofei Xie +2
We propose a new efficient algorithm to obtain the locally minimal generating set of the syzygies for an ideal, i.e. a generating set whose proper subsets cannot be generating sets…
Top-forms of Leading Singularities in Nonplanar Multi-loop Amplitudes
Baoyi Chen, Gang Chen, Yeuk-Kwan E. Cheung +2
The on-shell diagram is a very important tool in studying scattering amplitudes. In this paper we discuss the on-shell diagrams without external BCFW-bridges. We introduce an extra…
Top-forms of Leading Singularities in Nonplanar Multi-loop Amplitudes
Baoyi Chen, Gang Chen, Yeuk-Kwan E. Cheung +2
Bipartite on-shell diagrams are the latest tool in constructing scattering amplitudes. In this paper we prove that a Britto-Cachazo-Feng-Witten (BCFW)-decomposable on-shell diagram…
