Detailed Description

Inelasticity distributions: stores parametrizations and picks inelasticities.

Constructor & Destructor Documentation

Y()

Y::Y

(

)

The Y class contains all of the parameterizations for generating inelasticity distributions We are following Connolly et al. (2011) but any model can be added.

Member Function Documentation

Getyweight()

double Y::Getyweight	(	double	pnu,
		double	y,
		int	nu_nubar,
		int	currentint
	)

If you want to choose y from a flat distribution this is the weight it should have according to Connolly et al. (2011)

pickY()

double Y::pickY	(	Settings *	settings1,
		double	pnu,
		int	nu_nubar,
		int	currentint
	)

pick inelasticity y according to chosen model

Pick an inelasticity y according to the model chosen.

pickYConnollyetal2011()

double Y::pickYConnollyetal2011 ( int  NU, int  CURRENT, double  e  )

private

pick an inelasticity using recipe in Connolly et al. (2011)

pickYGandhietal()

double Y::pickYGandhietal ( )

private

THIS IS A ROUGH PARAMETRIZATION OF PLOT 6 FROM Ghandhi,Reno,Quigg,Sarcevic hep-ph/9512364 (the curves are not in their later article). There is also a slow energy dependence.
