Detailed Description

Interface to the HIJING event generator.

StarHijing provides the user interface for steering the HIJING event generator, and provides the connection between HIJING and the concrete Monte Carlo application.

To configure HIJING for a particular simulation, the user should refer to the HIJING manual: http://ntc0.lbl.gov/~xnwang/hijing/.

The HIPARNT, HIMAIN1, HIMAIN2 and LUDAT3 common blocks have been exposed as C structures.

Example:

Examples:
/macros/starsim.hijing.C.

Definition at line 48 of file StarHijing.h.

Member Function Documentation

Int_t StarHijing::Generate ( )
virtual

Developers must provide a generate method. In this method, the event generation machinery should be called. It is expected that the event record is filled in the Generate method, so that particles and event characteristics are available to subsequent generators and the primary generator maker. The primary maker is responsible for pushing particles out to the concrete simulation package.

Implements StarGenerator.

Int_t StarHijing::Init ( )
virtual

Developer must provide initialization routine. This method should call any functions, subroutines and/or methods on the concrete event generator necessary for its initialization.

These particles will be decayed by geant instead of hijing

Int_t StarHijing::LuComp ( Int_t  jetsetid)

Returns the compressed particle code (used in mdcy, mdme,... ) from the jetset id of the particle

Definition at line 92 of file StarHijing.cxx.

Int_t StarHijing::pdgid ( const Int_t &  code)
protected

Given the event generator's native particle code, returns the corresponding PDG code

Parameters
