 Some thoughts regarding the filter framework for the new event generator framework

New event generators are now being implemented in a C++ framework, enabling us to run simulations within the standard STAR, ROOT-based production chain.  Running these generators requires us

STARSIM is the legacy simulation package in STAR, implemented in FORtran, MORtran and utilizing GEANT3 as the concrete MC package.    For documentation on how to run simulations using S

Event generators currently integrated into starsim using the root4star framework (11/29/12):

• Pythia 6.4.23
• Pythia 8.1.62
• Hijing 1.383

Event generators are responsible for creating the final state particles which are fed out to GEANT for simulation.  They can be as simple as particle guns, shooting individual particles along well defined trajectories, or complex hydrodynamical models of heavy-ion collisions.  Regardless of the complexities of the underlying physical model, the job of an event generator in the STAR framework is to add particles to an event record.  In this document we will describe the steps needed to add a new event generator to the STAR framework.  The document will be divided into three sections: (1)  An overview, presenting the general steps which are required; (2) A FORtran-specific HOWTO, providing guidance specific to the problem of interfacing FORtran with a C++ application; and (3) A document describing the STAR event record.
