get_spin_correlation_rcl

get_spin_correlation_rcl(npr, order='LO', pow=None, als=None)

Extracts the computed value of the spin-correlated summed squared amplitude.

Parameters

• npr (int) – process number

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

• pow/gs (int[]) – array with values representing the powers in fundamental couplings in the order as dictated by the model file, e.g. [2, 3] \(\equiv g_\mathrm{s}^2 e^3\), or, if supported by the model, the power in terms of \(g_\mathrm{s}\) only (power in \(e\) is determined automatically from the underlying process)

Returns

A2sc

Return type

(float)
