Detailed Description

Class that implements the efficiency description across the signal Dalitz plot.

Class that defines the efficiency model variation across the signal Dalitz plot. The phase space acceptance is determined from a weighted sum of LauAbsEffModel objects. This is useful for samples that contain two different categories of signal with different efficiencies. The efficiency variation is defined in terms of x = m_13^2, y = m_23^2 for the Dalitz plot (default) or x = m', y = theta' for the square Dalitz plot

Member Function Documentation

void LauWeightedSumEffModel::addEffModel	(	const LauAbsEffModel *	effModel,
		Double_t	coeff
	)

Add an efficiency variation across the phase space using a predetermined LauAbsEffModel object.

The efficiency is defined in terms of x = m_13^2, y = m_23^2 or x = m', y = theta' for the square Dalitz plot

Parameters

[in]	effModel	the LauAbsEffModel object that describes the efficiency variation
[in]	coeff	the coefficient to multiply this efficiency by

Determine the efficiency for a given point in the Dalitz plot.

The method uses the models set by the addEffModel() function and the vetoes information.

Parameters

[in] kinematics the object that defines the DP position

Returns: the efficiency value at the given point in the DP

Implements LauAbsEffModel.
