Member Function Documentation

void softsusy::QedQcd::calcPoleMb ( )

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

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.

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

beta functions of masses

double softsusy::QedQcd::qedBeta ( ) const

returns number of active flavours

QED beta function

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

sets a running quark mass

set mb(mb)
