Geant4 is a toolkit for the simulation of the passage of particles
through matter. Its areas of application include high energy,
nuclear and accelerator physics, as well as studies in medical and
space science. The two main reference papers for Geant4 are
published in Nuclear Instruments and Methods in Physics Research A
506 (2003) 250-303, and IEEE Transactions on Nuclear Science 53 No. 1
(2006) 270-278.
