HIP: Symbolic high-energy physics calculations
Alexander Hsieh, Eran Yehudai · Computers in Physics · 1992
HIP, a set of computer packages for symbolic calculation of Feynman diagrams, is presented. The packages were designed as an aid in calculating tree-level multiparticle electroweak production processes, though they can be used for a much wider class of calculations. The packages have been used to calculate such processes as eγ→Wν and γγ→W+W− at tree level with arbitrary Wγ couplings. The packages are written in the computer algebra language Mathematica, which provides a powerful working environment.
