In this article we derive new symbolic tools to gain large-scale computer understanding in QCD. Here we exploit the fact that hypergeometric structures in single and multiscale Feynman integrals emerge in a wide class of topologies. Using integration-by-parts relations, associated master or scalar integrals have to be calculated. For this purpose it appears useful to devise an automated method which recognizes the respective (partial) differential equations related to the corresponding higher transcendental functions. 2023-04-10T03:06:08Z 2023-04-10T03:06:08Z 2023 Book https://link.springer.com/article/10.1007/s10472-023-09831-8 https://dlib.phenikaa-uni.edu.vn/handle/PNK/7711 en application/pdf Springer
