It confirms what Vladimir said : you see charged particles or ions after they have lost their energy by ionization. If you run 1 event with /tracking/verbose 2, you will quickly understand what happen. To study hadronic interactions alone, you may play with example Hadr03, with macros like the one in attachement.
