Determination of Boundary Contributions in Recursion Relation
Bo Feng, Kang Zhou, Chenkai Qiao +1
In this paper, we propose a new algorithm to systematically determine the missing boundary contributions, when one uses the BCFW on-shell recursion relation to calculate tree ampli…

General tree-level amplitudes by factorization limits
Kang Zhou, Chenkai Qiao
To find boundary contributions is a rather difficult problem when applying the BCFW recursion relation. In this paper, we propose an approach to bypass this problem by calculating…
