چکیده
A bstract We present the two-loop leading colour QCD helicity amplitudes for process pp ? W ( l? ) ? + j . implement a complete reduction of amplitudes, including leptonic decay -boson, using finite field arithmetic, and extract analytic remainders recently identified basis special functions. Simplified expressions are obtained after considering permutations rational kinematic parametrisation multivariate partial fractioning. demonstrate efficient numerical evaluation summed physical kinematics, hence suitability phenomenological applications.

Two-loop helicity amplitudes for the production of two off-shell electroweak bosons in gluon fusion
We compute the part of the two-loop virtual amplitude for the process gg → V1V2 → (l1 l̄ ′ 1)(l2 l̄ ′ 2), where V1,2 are arbitrary electroweak gauge bosons, that receives contributions from loops of massless quarks. Invariant masses of electroweak bosons are allowed to be different from each other. Our result provides an important ingredient for improving the description of gluon fusion contribut...
متن کاملTwo-loop QCD helicity amplitudes for massless quark-quark scattering
We present the two-loop helicity amplitudes for the scattering of massless quarks in QCD. We use projector techniques to compute the coefficients of the general four-quark amplitude at up to two-loops in conventional dimensional regularisation and use these coefficients to derive the helicity amplitudes in the ’t Hooft-Veltman scheme. The structure of the infrared divergences agrees with that p...
متن کاملTwo-loop helicity amplitudes for fermion-fermion scattering
We discuss the calculation of two-loop helicity amplitudes for quark-quark scattering in QCD and four-gluino scattering in N = 1 supersymmetric Yang-Mills theory. We study the dependence of the results on different variants of dimensional regularization. In particular, we consider the ’t Hooft-Veltman and four-dimensional helicity (FDH) schemes. We also discuss ambiguities in continuing the Dir...
متن کاملhh j j production at the LHC
The search for di-Higgs production at the LHC in order to set limits on the Higgs trilinear coupling and constraints on new physics is one of the main motivations for the LHC high-luminosity phase. Recent experimental analyses suggest that such analyses will only be successful if information from a range of channels is included. We therefore investigate di-Higgs production in association with t...
متن کاملOne loop multiphoton helicity amplitudes.
We use the solutions to the recursion relations for double-off-shell fermion currents to compute helicity amplitudes for n-photon scattering and electronpositron annihilation to photons in the massless limit of QED. The form of these solutions is simple enough to allow all of the integrations to be performed explicitly. For n-photon scattering, we find that unless n = 4, the amplitudes for the ...
