CLASS
ShowerAlphaQED:
Base class:
Public members:
inline ShowerAlphaQED();
inline ShowerAlphaQED(const ShowerAlphaQED &);
virtual ~ShowerAlphaQED();
Standard ctors and dtor.
the following two methods are equivalent to the QCD ones
and are necessary to make use of the virtuality of ShowerAlpha
at other places.
virtual double value(const Energy2 scale);
It returns the running alpha value evaluated at the input scale
multiplied by the scale factor scaleFactor().
inline virtual double overestimateValue();
It returns the running alpha value evaluated at the input scale
multiplied by the scale factor scaleFactor().
static void Init();
Standard Init function used to initialize the interfaces.
Protected members:
inline virtual IBPtr clone() const;
inline virtual IBPtr fullclone() const;
Standard clone methods.
Private members:
static ClassDescription<ShowerAlphaQED> initShowerAlphaQED;
Describe an concrete class with persistent data.
ShowerAlphaQED & operator=(const ShowerAlphaQED &);
Private and non-existent assignment operator.
double _alpha;
