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…
Amplituhedra, and Beyond
Livia Ferro, Tomasz Lukowski
This review is a primer on recently established geometric methods for observables in quantum field theories. The main emphasis is on amplituhedra, i.e. geometries encoding scatteri…
Amplituhedron meets Jeffrey-Kirwan Residue
Livia Ferro, Tomasz Lukowski, Matteo Parisi
The tree amplituhedra are mathematical objects generalising the notion of polytopes into the Grassmannian. Proposed for as a geometric construction…
Harmonic R-matrices for Scattering Amplitudes and Spectral Regularization
Livia Ferro, Tomasz Lukowski, Carlo Meneghelli +2
Planar N=4 super Yang-Mills appears to be integrable. While this allows to find this theory's exact spectrum, integrability has hitherto been of no direct use for scattering amplit…
A Shortcut to the Q-Operator
Vladimir V. Bazhanov, Tomasz Lukowski, Carlo Meneghelli +1
Baxter's Q-operator is generally believed to be the most powerful tool for the exact diagonalization of integrable models. Curiously, it has hitherto not yet been properly construc…
