Geometry of in-in correlators
Ross Glew
We introduce a family of polytopes -- in-in zonotopes -- whose boundary structure organizes the contributions to scalar equal-time correlators in flat space computed via the in-in…
The Geometry of BCFW for ABJM Loop Integrands
Livia Ferro, Ross Glew, Tomasz Lukowski +1
In this paper we investigate the loop-level geometry of ABJM theory from the perspective of lightcone geometries in dual space. This geometry admits a natural fibration, where one…
Kinematic flow from the flow of cuts
Ross Glew, Andrzej Pokraka
The wavefunction coefficients of conformally coupled scalars in power-law FRW cosmologies satisfy differential equations governed by a set of simple combinatorial rules known as th…
Generalised wavefunction coefficients and acyclonesto-cosmohedra
Stefan Forcey, Ross Glew, Hyungrok Kim
Scattering amplitudes of theory can be encoded as the canonical form of the Stasheff associahedron. Similarly, the flat-space wavefunction coefficients of…
Singularities of massless scattering and cluster algebras
Lara Bossinger, James Drummond, Ross Glew +2
Partial flag varieties arise in the context of massless scattering kinematics. They can be associated to both spinor-helicity variables and momentum twistor variables in two separa…
Wavefunction coefficients from Amplitubes
Ross Glew
Given a graph its set of connected subgraphs (tubes) can be defined in two ways: either by considering subsets of edges, or by considering subsets of vertices. We refer to these as…
Amplitubes: Graph Cosmohedra
Ross Glew, Tomasz Lukowski
The tree-level scattering amplitudes for theory can be interpreted as a sum over the vertices of a polytope known as the associahedron. For each graph , there e…
Positive and Negative Ladders in Loop Space
Ross Glew, Tomasz Lukowski
Motivated by a new term-wise factorised formula for the two-loop MHV integrand for scattering amplitudes in super Yang-Mills (SYM), together with recent results for…
The Two-loop MHV Momentum Amplituhedron from Fibrations of Fibrations
Livia Ferro, Ross Glew, Tomasz Lukowski +1
Recently, a new approach to computing the canonical forms of the momentum amplituhedron in dual-momentum space was proposed by the authors. These are relevant for the integrands of…
Prescriptive Unitarity from Positive Geometries
Livia Ferro, Ross Glew, Tomasz Lukowski +1
In this paper, we define the momentum amplituhedron in the four-dimensional split-signature space of dual momenta. It encodes scattering amplitudes at tree level and loop integrand…
One-loop string amplitudes in AdSS: Mellin space and sphere splitting
F. Aprile, J. M. Drummond, R. Glew +1
We study string corrections to one-loop amplitudes of single-particle operators in . The tree-level correlators in supergravity enjoy an accidental 1…
