Member Function Documentation

◆ calcPoleMb()

void softsusy::QedQcd::calcPoleMb ( )

Calculates the pole mass from the running mass, which should be defined at mb

◆ getGaugeMu()

DoubleVector softsusy::QedQcd::getGaugeMu	(	const double	m2,
		const double	sinth
	)		const

This will calculate the three gauge couplings of the Standard Model at the scale m2. It's a simple one-loop calculation only and no thresholds are assumed. Range of validity is electroweak to top scale.

◆ massBeta()

void softsusy::QedQcd::massBeta ( DoubleVector & x ) const

beta functions of masses

◆ qedBeta()

double softsusy::QedQcd::qedBeta ( ) const

returns number of active flavours

QED beta function

◆ setMass()

void softsusy::QedQcd::setMass	(	mass	mno,
		double	m
	)

inline

sets a running quark mass

set mb(mb)
