StringInteractions is the base class for handling colour reconnection, swing, shoving, and rope-type models for modifying string fragmentation.
|
virtual |
The StringInteractions class.
Function called from Pythia after the basic pointers. The base class will setup the standard behaviour of Pythia 8.2 according to the given Settings. Derived classes should create objects of the specific model objects to be used.
The base class init() method only implements the ColourReconnection model from Pythia 8.2.
Reimplemented in Ropewalk.
|
protected |
The object responsible for colour reconections in the end of PartonLevel or in the beginning of HadronLevel.
|
protected |
The object responsible for the perturbative swing which is always active together with the TimeShower.
|
protected |
The object responsible for modifying fragmentation parameters due to string interactions in each break-up (eg. in rope hadronisation).
|
protected |
The object responsible for repulsion between strings before hadronisation (or calculating the repulsion before but actually pushing the hadrons after fragmentation).
