FIRECreateStartFile

FIRECreateStartFile[path] creates a FIRE .start file using the script CreateStartFile.m in path. To that aim a Mathematica kernel is started in the background via RunProcess. The function returns True if the evaluation succeeds and False otherwise.

Alternatively, one can use FIRECreateStartFile[path, topo] where topo is an FCTopology symbol and the full path is implied to be path/topoName/CreateStartFile.m.

If you need to process a list of topologies, following syntaxes are possible FIRECreateStartFile[{path1,path2, ...}], FIRECreateStartFile[path, {topo1, topo2, ...}]

The path to the Mathematica Kernel can be specified via FIREMathematicaKernelPath. The default value is Automatic.

topo = FCTopology["prop3lX1", {SFAD[{p1, m^2}], SFAD[p2], SFAD[{p3, m^2}], SFAD[Q - p1 - p2 - p3], SFAD[Q - p1 - p2], SFAD[Q - p1], SFAD[Q - p2], SFAD[p1 + p3], SFAD[p2 + p3]}, {p1, p2, p3}, {Q}, {}, {}]

\text{FCTopology}\left(\text{prop3lX1},\left\{\frac{1}{(\text{p1}^2-m^2+i \eta )},\frac{1}{(\text{p2}^2+i \eta )},\frac{1}{(\text{p3}^2-m^2+i \eta )},\frac{1}{((-\text{p1}-\text{p2}-\text{p3}+Q)^2+i \eta )},\frac{1}{((-\text{p1}-\text{p2}+Q)^2+i \eta )},\frac{1}{((Q-\text{p1})^2+i \eta )},\frac{1}{((Q-\text{p2})^2+i \eta )},\frac{1}{((\text{p1}+\text{p3})^2+i \eta )},\frac{1}{((\text{p2}+\text{p3})^2+i \eta )}\right\},\{\text{p1},\text{p2},\text{p3}\},\{Q\},\{\},\{\}\right)
