Title: A comprehensive comparison for simulations of cosmic-ray muons underground

The two leading simulation frameworks used for the simulation of cosmic-ray muons underground are FLUKA and Geant4. There have been in the past various questions raised as to the equivalence of these codes regarding cosmogenically produced neutrons and radioactivity in an underground environment. Many experiments choose one of these frameworks, and because they typically have different geometries or locations, the issues relating to code comparison are compounded. We report on an effort to compare the results of each of these codes in simulations which have simple geometry that is consistent between the two codes. It is seen that in terms of integrated neutron flux and neturon capture statistics the codes agree well in a broad sense. There are, however, differences that will be subject of further study. Comparisons of the simulations to available data are considered and the difficulties of such comparisons are pointed out.
