HEPMath - Semi-Automatic High Energy Physics Computations in Mathematica
HEPMath is a Mathematica package which facilitates the implementation of
computational algorithms for High Energy Physics in Mathematica. Its main
features are:
-
Consistent integration of tensors with symbolic indices and index
contractions in Mathematica, along with functions to manipulate (expand,
collect, differentiate etc.) such expressions. Arbitrary tensors and
index types can be defined by the user.
-
Implementation of the basic building blocks of Feynman amplitudes, such
as Dirac spinors, Dirac matrices, Lorentz vectors, colour matrices
etc. and their algebraic properties.
-
Computation of traces over Dirac matrices in 4 and D dimensions.
-
Simplification of colour structures.
- Manipulation of loop integrals such as automatic Feynman
parametrisation for multi-loop integrals or reduction of
one-loop integrals to Passarino-Veltman (tensor) integrals.
-
Seamless interfaces to FeynArts,
LoopTools and
LHAPDF.
-
Generation and compilation of numerical code, based on Mathematica's
Compile and CCodeGenerate functions.
-
Generation of Python extension modules which make the generated
functions callable from Python.
