Detailed Description

JunctionSplitting takes an event and seperate junction chains from each other, such that no junctions are colour connected to each other.

Member Function Documentation

bool checkColours ( Event event)

Test whether an event has a physical colour configuration. It also splits junction pairs into pieces that PYTHIA can hadronize.

Check that all colours are connected in physical way. Also split junction pairs, such that the hadronization can handle the configuration.

Not really a colour check, but a check all numbers are valid.

Check if any singlet gluons were made, and if so return false.

Need to try and split junction structures.

Try to split up the junction chains by splitting gluons

Remove junctions if more than 2 are connected.

Split up junction pairs.

Done checking.

void init ( )


Initialize the class and all the created classes.


Initialize auxiliary fragmentation classes.

Initialize string and ministring fragmentation.

For junction processing.

virtual void onInitInfoPtr ( )

If an object needs to set up infoPtr for sub objects, override this and call registerSubObject for each object in question.

Reimplemented from PhysicsBase.
