The AlphaEM class is an exact reimplementation of the electromagentic coupling in FORTRAN HERWIG and is mainly intended for testing.
It uses that same hadronic parameterisation as in the ThePEG::SimpleEM but differs in the treatment of the top and leptonic contribution.
|
inline |
|
protectedvirtual |
Make a simple clone of this object.
Implements ThePEG::InterfacedBase.
|
protectedvirtual |
Initialize this object after the setup phase before saving an EventGenerator to disk.
InitException | if object could not be initialized properly. |
Reimplemented from ThePEG::InterfacedBase.
|
protectedvirtual |
Make a clone of this object, possibly modifying the cloned object to make it sane.
Reimplemented from ThePEG::InterfacedBase.
|
static |
The standard Init function used to initialize the interfaces.
Called exactly once for each class by the class description system before the main function starts or when this class is dynamically loaded.
The assignment operator is private and must never be called.
In fact, it should not even be implemented.
void Herwig::AlphaEM::persistentInput | ( | PersistentIStream & | is, |
int | version | ||
) |
Function used to read in object persistently.
is | the persistent input stream read from. |
version | the version number of the object when written. |
void Herwig::AlphaEM::persistentOutput | ( | PersistentOStream & | os | ) | const |
Function used to write out object persistently.
os | the persistent output stream written to. |
|
protected |
The real part of the photon self-energy.
ratio | The ratio of the mass squared of the fermion to the scale squared, \(m^2/Q^2\). |
|
virtual |
The \(\alpha_{EM}\).
Return the value of the coupling at a given scale using the given standard model object, sm.
Implements ThePEG::RunningCoupling.
