摘要Based on the antithetic cancellation technique, we propose a numerical method to calculate the N-dimensional principal value integrals. This method is powerful for numerically evaluating a multi-dimensional Feynman parameter integral with the singularity which occurs in loop calculations of quantum field theories, when some internal lines of the related Feynman diagrams are allowed by kinematics to approach to the corresponding mass shells.
