Member Function Documentation

void QedQcd::calcPoleMb

(

)

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

DoubleVector 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.
