void | setMass (mass mno, double m) |
sets a running quark mass | |
void | setAlpha (leGauge ai, double ap) |
sets QED or QCD structure constant | |
void | set (const DoubleVector &) |
For exporting beta functions to Runge-Kutta. | |
double | displayPoleMt () const |

double | displayPoleMb () const |
Returns bottom "pole" mass. | |
DoubleVector | displayMass () const |
Returns a vector of running fermion masses. | |
double | displayMass (mass mno) const |
Returns a single running mass. | |
double | displayAlpha (leGauge ai) const |
Returns a single gauge structure constant. | |
DoubleVector | display () const |
Obgligatory: returns vector of all running parameters. | |
double | qedBeta () const |
QED beta function. | |
double | qcdBeta () const |
QCD beta function. | |
void | massBeta (DoubleVector &) const |
DoubleVector | beta () const |
Beta functions of both beta-functions and all MSbar masses. | |
void | runGauge (double start, double end) |
Does not run the masses, just gauge couplings from start to end. | |
double | extractPoleMb (double asMb) |
calculates pole bottom mass given alpha_s(Mb)^{MSbar} from running b mass | |
double | extractRunningMb (double asMb) |
Done at pole mb: extracts running mb(polemb). | |
void | calcRunningMb () |
calculates running bottom mass given alpha_s(Mb)^{MSbar} from pole m_b | |
void | calcPoleMb () |
void | toMt () |
Evolves object to running top mass. | |
void | toMz () |
Evolves object to MZ. | |
DoubleVector | getGaugeMu (const double m2, const double sinth) const |
|
Calculates the pole mass from the running mass, which should be defined at mb |
|
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. |
