getscalarff()

void EvtBCLFF::getscalarff	(	EvtId	parent,
		EvtId	daughter,
		double	t,
		double	,
		double *	fpf,
		double *	f0f
	)

Scalar FF's.

Implementation follows arXiv:1509.06938v3.

For the scalar FF, the arglist in the constructor should contain 8 expansion parameters: b+_0, b+_1, b+_2, b+_3, b0_0, b0_1, b0_2, b0_3

Parameters

parent
daughter
t	Momentum transfer, also called q2. q2 = (p_B - p_M)^2
fpf	f_+(q2).
f0f	f_0(q2).

gettensorff()

void EvtBCLFF::gettensorff	(	EvtId	parent,
		EvtId	daughter,
		double	t,
		double	,
		double *	hf,
		double *	kf,
		double *	bp,
		double *	bm
	)

Not Implemented.

getvectorff()

void EvtBCLFF::getvectorff	(	EvtId	parent,
		EvtId	daughter,
		double	t,
		double	,
		double *	a1f,
		double *	a2f,
		double *	vf,
		double *	a0f
	)

Vector FF's.

Implementation follows arXiv:1503.05534v3. It is assumed that each expansion has three terms (hardcoded). However, this can be easily expanded or generalized. It is not done, because this way we can check if the number of arguments in the decay file is the correct one.

For the vector FF, the arglist in the constructor should contain 11 expansion parameters: A0_1, A0_2, A1_0, A1_1, A1_2, A12_0, A12_1, A12_2, V_0, V_1, V_2 Nota bene: A0_0 is correlated to A12_0.

Parameters

parent
daughter
t	Momentum transfer, also called q2. q2 = (p_B - p_M)^2
a1f	A1(q2)
a2f	A2(q2)
vf	V(q2)
a0f	A0(q2)
