Detailed Description

HeavyIons contains several standard Pythia objects to allow for the combination of different kinds of nucleon-nucleon events into a heavy ion collision event. The actual model for doing this must be implemented in a subclass overriding the the virtual'init()' and 'next()' functions.

Constructor & Destructor Documentation

Pythia8::HeavyIons::HeavyIons ( Pythia & mainPythiaIn )

inline

The constructor needs a reference to the main Pythia object to which it will belong. A HeavyIons object cannot belong to more than one main Pythia object.

Definition at line 37 of file HeavyIons.h.

References hiinfo, and mainPythiaPtr.

void Pythia8::HeavyIons::addSpecialSettings ( Settings & settings )

void Pythia8::HeavyIons::clearProcessLevel ( Pythia & pyt )

protected

If subclasses has additional Pythia objects for generating minimum bias nucleon collisions and the main Pythia object is set up to generated a hard signal process, this function can be used to clear all selected processes in a clone of the main Pythia object.

virtual bool Pythia8::HeavyIons::init ( )

pure virtual

Virtual function to be implemented in a subclass. This will be called in the beginning of the Pythia::init function if the mode HeavyIon:mode is set non zero. The return value should be true if this object is able to handle the requested collision type. If false Pythia::init will set HeavyIon:mode to zero but will try to cope anyway.

Implemented in Pythia8::Angantyr, and Pythia8::Angantyr.

virtual bool Pythia8::HeavyIons::init ( )

pure virtual

Virtual function to be implemented in a subclass. This will be called in the beginning of the Pythia::init function if the mode HeavyIon:mode is set non zero. The return value should be true if this object is able to handle the requested collision type. If false Pythia::init will set HeavyIon:mode to zero but will try to cope anyway.

Implemented in Pythia8::Angantyr, and Pythia8::Angantyr.

bool Pythia8::HeavyIons::isHeavyIon ( Settings & settings )

static bool Pythia8::HeavyIons::isHeavyIon ( Settings & settings )

static

Return true if the beams in the Primary Pythia object contains heavy ions.

virtual bool Pythia8::HeavyIons::next ( )

pure virtual

Virtual function to be implemented in a subclass. This will be called in the beginning of the Pythia::next function if HeavyIon:mode is set non zero. After the call, Pythia::next will return immediately with the return value of this function.

Implemented in Pythia8::Angantyr, and Pythia8::Angantyr.

virtual bool Pythia8::HeavyIons::next ( )

pure virtual

Virtual function to be implemented in a subclass. This will be called in the beginning of the Pythia::next function if HeavyIon:mode is set non zero. After the call, Pythia::next will return immediately with the return value of this function.
