Elliptic polylogarithms and iterated integrals on elliptic curves I: general formalism
Johannes Broedel, Claude Duhr, Falko Dulat +1
We introduce a class of iterated integrals, defined through a set of linearly independent integration kernels on elliptic curves. As a direct generalisation of multiple polylogarit…
Non-perturbative constraints on the quark and ghost propagators
Peter Lowdon
In QCD both the quark and ghost propagators are important for governing the non-perturbative dynamics of the theory. It turns out that the dynamical properties of the quark and gho…
Rigorous constraints on the matrix elements of the energy-momentum tensor
Peter Lowdon, Kelly Yu-Ju Chiu, Stanley J. Brodsky
The structure of the matrix elements of the energy-momentum tensor play an important role in determining the properties of the form factors , and wh…
Maximal Cuts in Arbitrary Dimension
Jorrit Bosma, Mads Sogaard, Yang Zhang
We develop a systematic procedure for computing maximal unitarity cuts of multiloop Feynman integrals in arbitrary dimension. Our approach is based on the Baikov representation in…
Gluing Ladders into Fishnets
Benjamin Basso, Lance J. Dixon
We use integrability at weak coupling to compute fishnet diagrams for four-point correlation functions in planar theory. The results are always multi-linear combinations of l…
Entropy evolution of moving mirrors and the information loss problem
Pisin Chen, Dong-han Yeom
We investigate the entanglement entropy and the information flow of two-dimensional moving mirrors. Here we point out that various mirror trajectories can help to mimic different c…
