rescale_colour_correlation_rcl

rescale_colour_correlation_rcl(npr, i1, i2, order='LO')

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

Parameters
  • npr (int) – process number

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

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

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

Returns

\(A^2_{cc}\)

Return type

(float)
