rescale_spin_colour_correlation_rcl

rescale_spin_colour_correlation_rcl(npr, i1, i2, v, order='LO')

Adjusts the results for a (new) value of \(\alpha_\mathrm{s}\), rescaling the structure-dressed helicity amplitudes and recomputing the spin-colour-correlated summed squared amplitude for the process with process number npr.

Parameters

• npr (int) – process number

• i1 (int) – gluon at leg i1

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

• v (complex[4]) – polarization vector

• order (str) – either ‘LO’ (default) or ‘NLO’

Returns

\(A^2_{scc}\)

Return type

(float)
