Geant4 Physics Lists

Update

• New Simple and Fast List for getting started with Geant4
• Space Sciences List (updated from GLAST physics list)

Introduction

In the development of a Geant4-based application, it is the user's responsibility to decide which physics processes are required, and then to include them in the physics list. A description of Geant4 physics lists and their use, along with simple and detailed examples, can be found in the Geant4 Application Developer's Guide .

In realistic applications the physics list can become long and involved. Also, the large number of physics processes available can make the choice difficult. For this reason the Geant4 group at SLAC has developed and supports a number of physics lists which can be copied by users and integrated into their applications. Each physics list has been specialized for a given area of application. Physics list support consists of

• development of prototype physics lists,
• testing based on simple examples,
• updating the lists as new Geant4 releases become available and
• validation against experimental data.

Available Physics Lists

Current physics lists include those developed to support experiments based at least in part at SLAC. These are:

Vertex/tracker/calorimeter for B physics (BaBar)	Space Sciences and Astrophysics Applications
High energy tracker/calorimeter for colliders (ILC)	Space Electronics Applications Physics List
Simple and Fast Physics List - for getting started	General Physics List with Model Selection
