Antenna subtraction at NNLO
TL;DR: In this article, a subtraction scheme relevant for NNLO perturbative calculations in e+e−→ jets is presented, where antenna functions derived from the matrix elements for tree-level 1→3 and 1→4 and one-loop 1-3 processes are constructed.

Antenna Subtraction at NNLO
TL;DR: In this paper, a subtraction scheme was proposed for NNLO perturbative calculations in $e^+e^- \to $ jets, where the antenna functions were derived from the matrix elements for tree-level $1\to 3$ and $1 \to 4$ and one-loop one-to-three$ processes.

Integration by parts: The algorithm to calculate β-functions in 4 loops
K.G. Chetyrkin,F.V. Tkachov +1 more
TL;DR: In this paper, it was proved that the counterterm for an arbitrary 4-loop Feynman diagram in an arbitrary model is calculable within the minimal subtraction scheme in terms of rational numbers and the Riemann ζ-function in a finite number of steps via a systematic "algebraic" procedure involving neither integration of elementary, special, or any other functions, nor expansions in and summation of infinite series of any kind.

One-loop n-point gauge theory amplitudes, unitarity and collinear limits
TL;DR: In this article, the authors presented a technique which utilizes unitarity and collinear limits to construct ansatze for one-loop amplitudes in gauge theory, and proved that their N = 4 ansatz is correct.
