DipoleIndex is used to index splitting generators for a particular dipole.
DipoleSplittingInfo contains all parameters to generate a full dipole splitting.
DipoleSplittingKernel is the base class for all kernels used within the dipole shower.
FIgx2qqxDipoleKernel implements the g -> qqbar splitting off a final-initial dipole.
virtual double evaluate(const DipoleSplittingInfo &) const
Evaluate this splitting kernel for the given dipole splitting.
virtual IBPtr clone() const
Make a simple clone of this object.
void persistentOutput(PersistentOStream &os) const
Function used to write out object persistently.
FIgx2qqxDipoleKernel()
The default constructor.
virtual DecayMEPtr matrixElement(const DipoleSplittingInfo &dInfo) const
Return the completely spin-unaveraged (i.e.
static ClassDescription< FIgx2qqxDipoleKernel > initFIgx2qqxDipoleKernel
The static object used to initialize the description of this class.

FIgx2qqxDipoleKernel & operator=(const FIgx2qqxDipoleKernel &)=delete
The assignment operator is private and must never be called.
virtual bool canHandleEquivalent(const DipoleIndex &a, const DipoleSplittingKernel &sk, const DipoleIndex &b) const
Return true, if this splitting kernel is the same for the given index a, as the given splitting kerne...
void persistentInput(PersistentIStream &is, int version)
Function used to read in object persistently.
virtual tcPDPtr emission(const DipoleIndex &) const
Return the emission data after splitting, given a dipole index.
virtual IBPtr fullclone() const
Make a clone of this object, possibly modifying the cloned object to make it sane.
virtual tcPDPtr spectator(const DipoleIndex &) const
Return the spectator data after splitting, given a dipole index.
static void Init()
The standard Init function used to initialize the interfaces.
virtual bool canHandle(const DipoleIndex &) const
Return true, if this splitting kernel applies to the given dipole index.
virtual tcPDPtr emitter(const DipoleIndex &) const
Return the emitter data after splitting, given a dipole index.
