A portable implementation of one-loop Feynman integrals

We present the first performance-portable implementation of a loop integral library for high-energy particle physics. The new code is based on the QCDLoop package, which provides an essential component in the software stack for perturbative precision calculations at collider experiments. Our implementation extends QCDLoop to modern computing architectures by means of the Kokkos portability framework, which allows to target most existing CPUs and GPUs.
