cLTD

A Mathematica package that allows computing the cLTD expression using FROM.

• Supports general expression with arbitrary numerators.
• Support of multi-core using tform with the number of cores specified with the FORMcores option.
• Allows optimizing the run for when no numerator is present through the NoNumerator option.
• Allows the generation of the standard LTD expression with the stdLTD option.

The proof and implementation of the algorithm can be found in the at Manifestly Causal Loop-Tree Duality.
