Description

In this paper, we introduced QFT++, a C++ toolkit for numerical calculation of quantum field theory. By comparing the result from QFT++ with the traditional calculation result of the Feynman amplitude pp¯ → mΦ, the validity of QFT++ was demonstrated. Furthermore, the toolkit was optimized in a fixed convention, in which a significant improvement of performance was found. The optimized version will be used in the partial wave analysis (PWA) of hadron spectroscopy, where the computation speed is a crucial bottleneck in most cases. (author)
