Abstract
Here, we attempt to summarize the activities of Track 3 of the 17th International Workshop on Advanced Computing and Analysis Techniques in Physics Research (ACAT 2016).
Highlights
Today’s computations in theoretical high energy physics (HEP) are hardly feasible without the use of modern computer tools and advanced computational algorithms
As a matter of fact, the processes of interest that are accessible at present colliders are typically rather complicated; as such, from the theoretical side, one needs to deal with high multiplicities, and be able to go beyond leading-order approximations in order to adequately match the high precision of experimental data
While most of the presented topics are closely interrelated, for the sake of this summary we decided to divide them into three main categories: computer algebra tools, algorithms for multi-loop computations and applications to physical processes
Summary
Today’s computations in theoretical high energy physics (HEP) are hardly feasible without the use of modern computer tools and advanced computational algorithms. It uses FeynArts [6] to generate diagrams for the process of interest, passes them to FORM, which performs the d-dimensional Dirac algebra and other things required for computing one-loop amplitudes, and it produces optimized FORTRAN code, which can be compiled and run in order to obtain the cross section and cross section distributions for the process.
