Function to calculate the correct running coupling/2*Pi value, including renormalisation scale variations + threshold matching.
Function to calculate the correct alphaem/2*Pi value, including renormalisation scale variations + threshold matching.
Get alphaEM(k*pT^2) and subtractions.
Done.

inlinevirtual |
Return the value of the coupling that should be used for this branching. Note that the last input allows easy access to the PS evolution variable. return values -1 –> Coupling value not defined. double > 0 –> Value to be used for this branching.
Return coupling. Set up such the argument is NOT RESCALED in as2Pi function - rather guarantee that INPUT pT2/scale has desired value.
Reimplemented from DireSplittingQCD.
|
inlinevirtual |
Return an identifier for the interaction that causes the branching. return values -1 –> Type not defined. 1 –> QCD splitting (i.e. proportional to alphaS) 2 –> QED splitting (i.e. proportional to alphaEM) 3 –> EW splitting (i.e. proportional to sinThetaW) 4 –> Yukawa splitting (i.e. proportional to y)
Reimplemented from DireSplittingQCD.

inlinevirtual |
Return a pair of ids for the radiator and emission after the splitting.
Reimplemented from DireSplittingQCD.
