abstract

We review techniques for more efficient computation of perturbative scattering amplitudes in gauge theory, in particular tree and one-loop multi-parton amplitudes in QCD. We emphasize the advantages of (1) using color and helicity information to decompose amplitudes into smaller gauge-invariant pieces, and (2) exploiting the analytic properties of these pieces, namely their cuts and poles. Other useful tools include recursion relations, special gauges and supersymmetric rearrangements.

On the amplitude expansion of gluon correlators in $\textrm{AdS}_4$

hep-th · 2026-06-22 · unverdicted · novelty 7.0

Tree-level gluon correlators in AdS4 decompose into energy poles with residues given by flat-space amplitudes, curvature corrections captured by lower-point amplitudes with merged data via AdS Berends-Giele currents.

Five-dimensional Geometry from Spinning Amplitudes

hep-th · 2026-05-28 · unverdicted · novelty 7.0

The classical limit of five-dimensional spinning amplitudes reproduces the multipole expansion of five-dimensional black holes after augmenting with the Hodge dual of the spin tensor, and identifies amplitudes corresponding to the Myers-Perry solution.

Tree Amplitudes with Charged Matter in Pure Gauge Theory

hep-th · 2026-04-20 · unverdicted · novelty 6.0

A new Mathematica package computes tree amplitudes with arbitrary gauge bosons and arbitrarily charged massless fermions by reducing distinct-flavor partial amplitudes to linear combinations of single-flavor supersymmetric Yang-Mills components.

Perturbiner methods in scattering amplitude

hep-th · 2026-07-07 · accept · novelty 5.5

Perturbiner multi-particle solutions of classical field equations generate Berends–Giele currents and tree-level amplitudes across scalars, gauge theory, gravity, NLSM, AdS, and one-loop integrands, including several unpublished recursions.
