A 100 GeV/c pi- beam is incident upon a Au target. Rapidity distributions of the final state pi- and pi+ are plotted.

Simulation Conditions

• Geant4 version: 8.1
• Models: QGS

Comments

• Filled points: data, open points: QGS model
• pi- rapidity: good agreement except at peak where prediction over-estimates by 15%.
• pi+ rapidity: good agreement at all rapidities greater than 0. Less than 0, the model under-estimates by factors of 5 or more.
