96. Renormalization of twist-two operators and its application

Tongzhi Yang

In this talk, we will first present the renormalization of twist-two operators in covariant gauge. And then we apply it to the computation of splitting functions in three-loop order.

79. Two-loop tensor integral coefficients in OpenLoops

Natalie Schär (PSI)

5/14/22, 2:45 PM

Numerical tools, such as OpenLoops, compute NLO scattering amplitudes in a fully automated way. In order to meet the precision requirements of the LHC era and future experiments, however, NNLO calculations are crucial, and their automation in a similar tool highly desirable.

In the OpenLoops framework, D-dimensional two-loop amplitudes are decomposed into loop momentum tensor integrals and...
