Hidden Amplitude Zeros From Double Copy
Christoph Bartsch, Taro V. Brown, Karol Kampf +3
Recently, Arkani-Hamed et al. proposed the existence of zeros in scattering amplitudes in certain quantum field theories including the cubic adjoint scalar theory Tr(), the $S…

Loops of Loops Expansion in the Amplituhedron
Taro V. Brown, Umut Oktem, Shruti Paranjape +1
We study a novel geometric expansion for scattering amplitudes in the planar sector of N=4 super Yang-Mills theory, in the context of the Amplituhedron which reproduces the all-loo…

Scalar BCJ Bootstrap
Taro V. Brown, Karol Kampf, Umut Oktem +2
In this letter, we study tree-level scattering amplitudes of scalar particles in the context of effective field theories. We use tools similar to the soft bootstrap to build an ans…
