Recursion Relation for Boundary Contribution
Qingjun Jin, Bo Feng
It is well known that under a BCFW-deformation, there is a boundary contribution when the amplitude scales as O(1) or worse. We show that boundary contributions have a similar recu…
Note on New KLT relations
Bo Feng, Song He, Rijun Huang +1
In this short note, we present two results about KLT relations discussed in recent several papers. Our first result is the re-derivation of Mason-Skinner MHV amplitude by applying…
New Identities among Gauge Theory Amplitudes
N. E. J. Bjerrum-Bohr, Poul H. Damgaard, Bo Feng +1
Color-ordered amplitudes in gauge theories satisfy non-linear identities involving amplitude products of different helicity configurations. We consider the origin of such identitie…
Gravity and Yang-Mills Amplitude Relations
N. E. J. Bjerrum-Bohr, Poul H. Damgaard, Bo Feng +1
Using only general features of the S-matrix and quantum field theory, we prove by induction the Kawai-Lewellen-Tye relations that link products of gauge theory amplitudes to gravit…
Gauge Amplitude Identities by On-shell Recursion Relation in S-matrix Program
Bo Feng, Rijun Huang, Yin Jia
Using only the Britto-Cachazo-Feng-Witten(BCFW) on-shell recursion relation we prove color-order reversed relation, -decoupling relation, Kleiss-Kuijf(KK) relation and Bern-C…
