RunningCoupling an abstract base class unifying the treatment of running couplings in ThePEG.
Definition at line 27 of file RunningCoupling.h.
|
inlinevirtual |
Return the number of loops contributing to the running this coupling.
The default returns zero to ensure backward compatibility.
Reimplemented in ThePEG::O1AlphaS, and ThePEG::SimpleAlphaEM.
Definition at line 50 of file RunningCoupling.h.
|
inlinevirtual |
Return an overestimate to the running coupling at the given scale.
This is defined to aid veto algorithms and by default returns the coupling itself, using the EventGenerators's StandardModelBase object.
