Automatic generation of Feynman graphs and amplitudes in QED

Description

Title of program: GRAND Catalogue Id: AATD_v1_0 Nature of problem In the calculation of quantum electro-dynamics (QED), it is necessary to enumerate Feynman graphs for each reaction. The number of graphs increases rapidly as order of perturbation grows. A large amount of calculation based on QED is required in the recent high energy physics. Versions of this program held in the CPC repository in Mendeley Data AATD_v1_0; GRAND; 10.1016/0010-4655(87)90212-8 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
