abstract

We present an analytic computation of the two-loop QCD corrections to $u\bar{d}\to W^+b\bar{b}$ for an on-shell $W$-boson using the leading colour and massless bottom quark approximations. We perform an integration-by-parts reduction of the unpolarised squared matrix element using finite field reconstruction techniques and identify an independent basis of special functions that allows an analytic subtraction of the infrared and ultraviolet poles. This basis is valid for all planar topologies for five-particle scattering with an off-shell leg.

  1. Complete function space for planar two-loop six-particle scattering amplitudes

    hep-ph 2025-01 conditional novelty 8.0 of 10

    Planar two-loop six-particle massless master integrals are solved analytically up to weight four as Chen iterated integrals, with a complete 245-letter alphabet and a validated numerical implementation.

  2. Two-loop amplitude for $t\bar{t}W$ production at hadron colliders in the leading colour approximation

    hep-ph 2026-08 conditional novelty 7.0 of 10

    The leading-colour two-loop QCD amplitude for ttbar-W production is evaluated numerically at phase-space points using differential equations and finite-field rational reconstruction.

  3. Top-Yukawa contributions to $pp\to b\bar{b}H$: two-loop leading-colour amplitudes

    hep-ph 2026-03 accept novelty 7.0 of 10

    First analytic two-loop leading-colour amplitudes for top-Yukawa-induced b bbar H production in the heavy-top limit, with Mathematica and C++ code.

  4. The structure of quark mass corrections in the $gg \rightarrow HH$ amplitude at high-energy

    hep-ph 2024-12 conditional novelty 7.0 of 10

    The leading-power mass logarithms in high-energy gg to HH are shown to originate solely from top-quark mass renormalization, enabling a resummation that sharply reduces the mass-scheme uncertainty of the virtual amplitude.

  5. Rational-function interpolation from p-adic evaluations in scattering amplitude calculations

    hep-ph 2024-12 conditional novelty 3.0 of 10

    A p-adic interpolation method reconstructs loop-amplitude rational functions directly in partial-fractioned form, cutting required probes by about 25x and output size by about 134x on a challenging two-loop five-point...
