Simulation
This chapter is devoted to Monte Carlo simulation of stochastic processes, both fundamental processes and those involving radiation transport through macroscopic material. The computation of fundamental processes builds on the treatment of rotations and Lorentz transformations from the previous chapter and expands it with a discussion of computational techniques for the evaluation of Feynman diagrams. The simulation of radiation transport covers electromagnetic processes such as ionization energy loss, bremsstrahlung, and pair production. A discussion of real-life challenges in the simulation of radiation transport is included, as well as a brief discussion of simulation toolkits that are available for solving industrial-strength problems. The discussion is intended to give an overview of some of the principal computational and numerical techniques enabling these toolkits.
