Constructor & Destructor Documentation

◆ MssmSoftPars() [1/2]

softsusy::MssmSoftPars::MssmSoftPars ( const MssmSoftPars & s )

Member Function Documentation

◆ addAmsb()

void softsusy::MssmSoftPars::addAmsb	(	const MssmSusy &	run,
		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

◆ anomalousDeriv()

void softsusy::MssmSoftPars::anomalousDeriv	(	const MssmSusy &	xx,
		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

◆ beta2()

MssmSoftPars softsusy::MssmSoftPars::beta2	(	const MssmSusy &	xx,
		sBrevity &	a
	)		const

Returns numerical beta functions of parameters and Brevity.

< dominant 3rd family approximation

< fully mixed case – slower

new dominant 3-family version

Old full 3-family version

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

◆ display()

void softsusy::MssmSoftPars::display	(	DoubleVector &	v,
		int &	k
	)		const

Obligatory function that outputs contents in v, k is incremented on output by the number of inputs.

◆ displayGaugino()

double softsusy::MssmSoftPars::displayGaugino ( int i ) const

Return \(M_{G_i}\)

◆ minimalGmsb()

void softsusy::MssmSoftPars::minimalGmsb	(	const MssmSusy &	xx,
		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

hep-ph/9801271

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

◆ setMh2Squared()

void softsusy::MssmSoftPars::setMh2Squared ( double f )

Sets \( m_{H_2}^2\)

◆ u1R_PQflip()

void softsusy::MssmSoftPars::u1R_PQflip ( MssmSusy & s )

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

◆ universal()

void softsusy::MssmSoftPars::universal	(	MssmSusy &	s,
		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
