Multi-Loop Negative Geometries
Lance J. Dixon, Umut Oktem, Shruti Paranjape +3
Scattering amplitudes in planar supersymmetric Yang-Mills theory are dual to expectation values of null polygonal Wilson loops. The Amplituhedron provides a geometric…
Grassmannian Geometries for Non-Planar On-Shell Diagrams
Artyom Lisitsyn, Umut Oktem, Melissa Sherman-Bennett +1
On-shell diagrams are gauge invariant quantities which play an important role in the description of scattering amplitudes. Based on the principles of generalized unitarity, they ar…
Uniqueness of MHV Gravity Amplitudes
Joris Koefler, Umut Oktem, Shruti Paranjape +2
We investigate MHV tree-level gravity amplitudes as defined on the spinor-helicity variety. Unlike their gluon counterparts, the gravity amplitudes do not have logarithmic singular…
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…
Poles At Infinity in On-shell Diagrams
Taro V. Brown, Umut Oktem, Jaroslav Trnka
In this paper we study on-shell diagrams in supersymmetric Yang-Mills (SYM) theory. These are on-shell gauge invariant objects which appear as cuts of loop integrand…
The Muon Smasher's Guide
Hind Al Ali, Nima Arkani-Hamed, Ian Banta +31
We lay out a comprehensive physics case for a future high-energy muon collider, exploring a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the advan…
