compute_colour_correlation_rcl(npr, p, i1, i2, order='LO')

Computes the colour-correlated summed squared amplitude, between particle with leg number i1 and particle with leg number i2, for the process with process number npr.

Parameters

• npr (int) – process number

• p (float[l][4]) – external momenta of the process with l legs

• i1 (int) – quark/anti-quark at leg i1

• i2 (int) – quark/anti-quark at leg i2

• order (str) – either 'LO' (default) or 'NLO'

Returns

(A2cc, momcheck)

Return type

(float, bool)
