This is an introduction to, and invitation to read, a series of review articles on scattering amplitudes in gauge theory, gravity, and superstring theory. Our aim is to provide an overview of the field, from basic aspects to a selection of current (2022) research and developments.

  1. QCD Scattering Amplitudes and Prescriptive Unitarity

    hep-th 2026-02 conditional novelty 7.0 of 10

    The maximally-transcendental part of planar two-loop six-gluon MHV QCD amplitudes is bootstrapped at symbol level and expressed in a 137-letter alphabet.

  2. Perturbations of Plane Waves and Quadratic Quasinormal Modes on the Lightring

    gr-qc 2025-09 conditional novelty 7.0 of 10

    Second-order gravitational perturbations on plane waves are solved with a GHP master equation and tensor harmonics, yielding quadratic quasinormal mode ratios and selection rules.

  3. Geometric Landau Analysis and Symbol Bootstrap

    hep-th 2025-08 unverdicted novelty 7.0 of 10

    Boundary structure of negative geometries, combined with Landau analysis, determines physical singularities and yields symbol alphabets for six-point two-loop and five-point three-loop ladder integrals in planar N=4 s...

  4. A Hidden Permutation Symmetry of Squared Amplitudes in ABJM Theory

    hep-th 2025-08 conditional novelty 7.0 of 10

    Squared ABJM amplitude integrands with fixed n+L are unified in a permutation-symmetric generating function, and a bipartite f-graph bootstrap yields new N=10 tree and loop results.

  5. Robustness of Starobinsky inflation in a minimal two-field scalar-tensor completion

    gr-qc 2026-04 unverdicted novelty 6.0 of 10

    Nearby trajectories in a minimal two-field scalar-tensor completion of Starobinsky inflation relax to an attractor where entropy sourcing is negligible, so observables remain effectively Starobinsky-like.

  6. Novel cluster-algebraic letters for 5- and 6-point QCD processes

    hep-th 2026-03 conditional novelty 6.0 of 10

    Candidate symbol alphabets for 5- and 6-point QCD processes are derived from the 9-particle N=4 super Yang-Mills cluster algebra, including new nested square-root letters.

  7. Subleading soft radiation during scattering of dressed states in QED

    hep-th 2025-11 conditional novelty 4.0 of 10

    With subleading-corrected Faddeev-Kulish dressing, tree-level QED bremsstrahlung below the dressing scale vanishes, and elastic dressed amplitudes equal the infrared-finite part of Fock amplitudes.
