BaBar Physics List

Last modified :

Description

The BaBar physics list contains the processes required to simulate B-physics events in the BaBar detector. The initial high-energy event is provided by a set of event generators chosen by the user. The simulation includes Bhabha scattering, dimuons, and the particles arising from B-decay. As a result the physics list processes and models have been chosen for an energy range of 9 GeV and below. The BaBar physics list is already quite mature and has been used since 2001 for the production of billions of simulated events.

A more detailed description of the BaBar physics list can be found here.

Getting the Physics List

The physics list directory can be downloaded as follows:

Test Modules

Several modules are provided as regression tests in order to compare physics results from release to release of Geant4. These modules are based on simplified detector geometries.

• Test1
• Test2

Validation

Validation tests are provided to compare physics results from experiments and test beams. These are based on realistic detector geometries. For each test a set of comparison plots are maintained.

• Test1
• Test2
