◆ ComputeCoeffDC1_K()

gslpp::vector< gslpp::complex > ** HeffDC1::ComputeCoeffDC1_K	(	double	mu,
		schemes	scheme = `NDR`
	)

a method returning the evolved Wilson related to \( D^{0} \, \rightarrow \, K^{+} \, K^{-} \)

it returns the Wilson coefficients of the process \( D^{0} \, \rightarrow \, K^{+} \, K^{-} \) evolved down to the low scale \( \mu \) with the associated coupling constants and CKM factors

Parameters

mu	a double for the low scale of the evolution
scheme	an enum "schemes" for the regularization scheme of the evolutor

Returns: a vector<complex> pointer to pointer method for the evolved Wilson coefficients
