Large-nf Contributions to the Four-Loop Splitting Functions in QCD
J. Davies, A. Vogt, B. Ruijl +2
We have computed the fourth-order nf^2 contributions to all three non-singlet quark-quark splitting functions and their four nf^3 flavour-singlet counterparts for the evolution of…
FORM, Diagrams and Topologies
Franz Herzog, Ben Ruijl, Takahiro Ueda +2
We discuss a number of FORM features that are essential in the automatic processing of very large numbers of diagrams as used in the Forcer program for 4-loop massless propagator d…
Forcer: a FORM program for 4-loop massless propagators
T. Ueda, B. Ruijl, J. A. M. Vermaseren
We present a new FORM program for analytically evaluating four-loop massless propagator-type Feynman integrals in an efficient way. Our program Forcer implements parametric reducti…
Why Local Search Excels in Expression Simplification
Ben Ruijl, Aske Plaat, Jos Vermaseren +1
Simplifying expressions is important to make numerical integration of large expressions from High Energy Physics tractable. To this end, Horner's method can be used. Finding suitab…
HEPGAME and the Simplification of Expressions
Ben Ruijl, Jos Vermaseren, Aske Plaat +1
Advances in high energy physics have created the need to increase computational capacity. Project HEPGAME was composed to address this challenge. One of the issues is that numerica…
