Description
pySecDec is a program to evaluate multi-loop Feynman integrals numerically based on the sector decomposition approach; its new release version 1.5 introduces features significantly improving its performance: automatic adaptive evaluation of weighted sums of integrals (e.g. amplitudes) and asymptotic expansion in kinematic ratios. I'd like to briefly review both, illustrating the expected performance benefits.
