Precision in Perturbative Particle Physics,ndard calculation of dimensionally regulated one-loop Feynman integrals; then we introduce the basic idea of using Mellin-Barnes representations to solve Feynman integrals in Euclidean and Minkowskian kinematic regimes.

Numerical Methods,d the construction of MB representations that take kinematic thresholds into account. Steepest descent and Lefschetz thimbles are applied to find optimal integration contours. The numerical evaluation of phase space . integrals is also briefly discussed.
