Detailed Description

Flatte PDF builder.

Build RooFlatte Pdf.

Config Directives:

/// configStr = Flatte ["<Optional Title>"]
/// x = AbsReal Def
/// mean  = AbsReal Def
/// g0 = AbsReal Def
/// m0a = AbsReal Def
/// m0b = AbsReal Def
/// g1 = AbsReal Def
/// m1a = AbsReal Def
/// m1b = AbsReal Def
/// 

x is the default observable. mean is the peak position of the pdf. g0 is the square of the coupling constant to the first channel (default = 0.1108 GeV) m0a is the mass of one of the final state particles in the first channel (default = 0.1108 GeV) m0b is the mass of other final state particle in the first channel (default = 0.13957 GeV) g1 is the square of the coupling constant to the first channel (default = 0.4229 GeV) m1a is the mass of one of the final state particles in the second channel (default = 0.49368 GeV) m1b is the mass of other final state particle in the second channel (default = 0.49368 GeV) After being defined, the four masses are held constant in the fit. All the floating variables can be RooRealVar or RooFormulaVar.

Constructor & Destructor Documentation

rarFlatte::rarFlatte

(

)

Trivial ctor.

Usually the objects should be created using other ctors.

Definition at line 38 of file rarFlatte.cc.

References init().

  : rarBasePdf(),
    _x(0), _mean(0), _g0(0), _m0a(0), _m0b(0), _g1(0), _m1a(0), _m1b(0)
{
  init();
}

rarFlatte::rarFlatte	(	const char *	configFile,
		const char *	configSec,
		const char *	configStr,
		rarDatasets *	theDatasets,
		RooDataSet *	theData,
		const char *	name,
		const char *	title
	)

Default ctor.

Parameters:

	configFile	The config file
	configSec	The config section
	configStr	The config string
	theDatasets	Available datasets
	theData	Default dataset for this PDF
	name	The name
	title	The title

The default ctor first initializes data members, and then calls init.

               theDatasets, theData, name, title),

void rarFlatte::init

(

)

[protected, virtual]

Initial function called by ctor.

init is called by the ctor. It first creates the parameters by calling createAbsReal, and finally it builds the RooFlatte PDF.

Reimplemented from rarBasePdf.

Definition at line 79 of file rarFlatte.cc.
