XjetAmps Project

This is the web page of the xjetamps project. We provide multiloop helicity amplitudes for the production of a massive boson and a jet at hadron colliders.

• Two-loop helicity amplitudes for H+jet production to higher orders in the dimensional regulator,
  which contains all the relevant one- and two-loop master integrals extended to weight 6 and the tree-level, one- and two-loop Hggg and Hgqq̄ helicity amplitudes extended to higher orders in ε,
  see the preprint 2301.10849 on the arXiv.
• Two-loop helicity amplitudes for V+jet production including axial vector couplings to higher orders in ε,
  which contains the tree-level, one- and two-loop helicity amplitudes for Vggg and Vgqq̄ with vector and axial vector couplings extended to higher orders in ε,
  see the preprint 2306.10170 on the arXiv.
• Planar three-loop QCD helicity amplitudes for V+jet production at hadron colliders,
  which contains the leading colour contributions to the Vgqq̄ helicity amplitudes at three loops,
  see the preprint 2307.15405 on the arXiv.
