This concrete class provides the definition of the pure virtual function value(scale) for \(\alpha_{\rm QED}\).
N.B. as we always use \(\alpha(0)\) for the radiation of photons this class is very simple.

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.
|
privatedelete |
The assignment operator is private and must never be called.
In fact, it should not even be implemented.
|

It returns the overestimiate of the coupling multiplied by the scale factor scaleFactor().
Implements Herwig::ShowerAlpha.
void Herwig::ShowerAlphaQED::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::ShowerAlphaQED::persistentOutput | ( | PersistentOStream & | os | ) | const |
Function used to write out object persistently.
os | the persistent output stream written to. |
|
virtual |
Return the ratio of the coupling at the scale to the overestimated value.
Implements Herwig::ShowerAlpha.
|
virtual |
Methods to return the coupling.
The methods are equivalent to the QCD ones and are necessary to make use of the virtuality of ShowerAlpha at other places. It returns the running coupling value evaluated at the input scale multiplied by the scale factor scaleFactor().
