Improvement and application of muon transport models implemented in the PHITS

Abe, Shinichiro   

Recently, muons are applied to various kinds of research fields, and the development of muon nuclear data is considered. Muon transport models are implemented into PHITS code However, the model for negative muon capture reaction is underestimate the measured data for productions of secondary particles. We will report the recent improvements of the model, the results of benchmarks, and the effect of the improvements of the models on the simulation of muon-induced soft errors.
