void SoftParsMssm::addAmsb ( double m32 )

Give it a SUSY object and a value of M3/2, and it will return a soft object with AMSB soft breaking terms. Note that the sleptons will be tachyonic, ie nothing has been done to fix that problem. Note that in the following, we are neglecting all Yukawa couplings except that of the third family.

three family version -- will be out by some two-loop terms. See hep-ph/9904378

void SoftParsMssm::anomalousDeriv	(	DoubleMatrix &	gEE,
		DoubleMatrix &	gLL,
		DoubleMatrix &	gQQ,
		DoubleMatrix &	gUU,
		DoubleMatrix &	gDD,
		double &	gH1H1,
		double &	gH2H2
	)		const

Returns derivatives of anomalous dimensions of fields with respect to renormalisation scale in MSSM for: RH leptons, LH leptons, LH quarks, RH up quarks, RH down quarks, H1 and H2 respectively

SoftParsMssm SoftParsMssm::beta2 ( ) const

Returns numerical beta functions of parameters.

< dominant 3rd family approximation

< fully mixed case -- slower

The following are valid in the third-family approximation -- they are much faster, and should be a good approximation to the no-mixed case

In the mixed case, we need to use the slower full 3-family expressions

Reimplemented in RpvSoftsusy.

double SoftParsMssm::displayGaugino ( int i ) const [inline]

Return $M_{G_i}$

void SoftParsMssm::minimalGmsb	(	int	n5,
		double	lambda,
		double	mMess,
		double	cgrav
	)

Boundary conditions to be applied at messenger scale for Gauge mediated SUSY breaking (see hep-ph/9703211 for example), n5 is the number of 5-plets, mMess is the messenger scale and lambda is the GMSB scale

There is a relative minus in the mGMSB conditions for gaugino masses, since these equations are for L=-M/2 lambda lambda. See hep-ph/9801271: BCA 27/7/12

void SoftParsMssm::setMh2Squared ( double f ) [inline]

Sets $m_{H_2}^2$

void SoftParsMssm::u1R_PQflip ( )

This flips the signs of various parameters (including mu) with no physical effect - apparently, through a U(1)_{R-PQ} transformation. See hep-ph/0312378

void SoftParsMssm::universal	(	double	m0,
		double	m12,
		double	a0,
		double	mu,
		double	m3sq
	)

Reads in universal boundary conditions at the current scale: m0, M1/2, A0, B-parameter and mu
