The covariant color-kinematics duality was proposed by Cheung and Mangan as a relation between the gauged bi-adjoint scalar theory and Yang-Mills theory. It holds at the level of the equations of motion and directly leads to a simple map between tree-level scattering amplitudes. I will show that this framework naturally incorporates higher-derivative
corrections. Moreover, it implies that the...

39. Generating Functions, Mellin Transformations and Twist-2 Operator Matrix Elements in QCD

Arnd Behring (CERN)

Twist-2 operators play an important role in QCD: they arise from the operator product expansion in deep-inelastic scattering and underlie the definition of collinear parton distribution functions (PDFs). We discuss the calculation of heavy quark contributions to matrix elements of these twist-2 operators at three-loop order in QCD. These matrix elements serve as matching coefficients to...
