From U(1) to E8: soft theorems in supergravity amplitudes
Wei-Ming Chen, Yu-tin Huang, Congkao Wen
It is known that for N=8 supergravity, the double-soft-scalar limit of a n-point amplitude is given by a sum of local SU(8) rotations acting on a (n-2)-point amplitude. For N<8 sup…
New fermionic soft theorems
Wei-Ming Chen, Yu-tin Huang, Congkao Wen
Soft limits of massless S-matrix are known to reflect symmetries of the theory. In particular for theories with Goldstone bosons, the double-soft limit of scalars reveals the coset…
Grassmannians for scattering amplitudes in 4d SYM and 3d ABJM
Henriette Elvang, Yu-tin Huang, Cynthia Keeler +4
Scattering amplitudes in 4d super Yang-Mills theory (SYM) can be described by Grassmannian contour integrals whose form depends on whether the external data is enco…
Integrable Amplitude Deformations for N=4 Super Yang-Mills and ABJM Theory
Till Bargheer, Yu-tin Huang, Florian Loebbert +1
We study Yangian-invariant deformations of scattering amplitudes in 4d N=4 supersymmetric Yang-Mills theory and 3d N=6 Aharony-Bergman-Jafferis-Maldacena (ABJM) theory. In particul…
More on Soft Theorems: Trees, Loops and Strings
Massimo Bianchi, Song He, Yu-tin Huang +1
We study soft theorems in a broader context, addressing their fate at loop level and their universality in effective field theories and string theory. We argue that for gauge theor…
Loop Corrections to Soft Theorems in Gauge Theories and Gravity
Song He, Yu-tin Huang, Congkao Wen
In this paper, we study loop corrections to the recently proposed new soft theorem of Cachazo-Strominger, for both gravity and gauge theory amplitudes. We first review the proof of…
