40	code to compute limits using FKS phase-space code to compute limits using FKS phase-space	Rikkert Frederix	4 years ago
39	cleanup of matrx_com3_col2.f95 code cleanup of matrx_com3_col2.f95 code	Rikkert Frederix	4 years ago

37	added a version with weyl fermions and a version with a colo... added a version with weyl fermions and a version with a color-map to optimize only leading (and leading subleading) terms	Rikkert Frederix	4 years ago

35	some small fixes in fund2 some small fixes in fund2	Rikkert Frederix	4 years ago
34	slight improvement in the color_algebra.f95 comments slight improvement in the color_algebra.f95 comments	Rikkert Frederix	4 years ago

31	cleaning cleaning	Rikkert Frederix	4 years ago

29	1st steps towards gg..g+1qqbar 1st steps towards gg..g+1qqbar	Rikkert Frederix	4 years ago
28	added matrix_fund.f95 and matrix_fund2.f95 (and color_algebr... added matrix_fund.f95 and matrix_fund2.f95 (and color_algebra.f95 needed by the latter) to compute the colour matrices in the fundamental representation (instead of using the colour flow basis). Much slower than matrix_com3.f95, in particular when using explicit matrix multiplication (as in matrix_fund.f95). But also using the color_algebra.f95 to simplify traces of colour matrices in the fundamental representation the computation of the colour factors is slower than evaluating the delta's as in matrix_com3.f95.	Rikkert Frederix	4 years ago

21	all set to 6 external particles with 100 PS points. All give... all set to 6 external particles with 100 PS points. All give identical results, but matrix_com3 is by far the fastest (mostly due to computing colour factors only once)	Rikkert Frederix	4 years ago
