Constructor & Destructor Documentation

◆ STU()

STU::STU ( const StandardModel & SM_i )

Constructor.

Parameters

[in] ?

Definition at line 12 of file STU.cpp.

: ThObservable(SM_i), myTHDM(static_cast<const THDM*> (&SM_i))
 
{
    mycache = new THDMcache(SM_i);
};

Member Function Documentation

◆ computeThValue()

double STU::computeThValue ( )

virtual

Empty constructor.

Implements ThObservable.

Reimplemented in DeltaS, DeltaT, and DeltaU.

Definition at line 19 of file STU.cpp.

{
    return 0.0;
}

◆ F()

double STU::F	(	const double	m02,
		const double	m12
	)		const

Function \(F(m02,m12)\) used for THDM. Remember that this function is defined for THDM while for SUSY we have a multiplicative factor 2.

Parameters

[in]	m02	mass square \(m_0^2\)
[in]	m12	mass square \(m_1^2\)

Returns: \(F(m02,m12)\)
