4. MUD response with CAL information Single beam (p, m) test • Observed muon signal by muon detector • Muons passing through the CAL • Pion leakage from CAL (punch through) e+e-→Z→qq (2 jets) event check • Number of muons produced in Jets • or created inside of the CAL Unfortunately, solenoid is set to air atJupiter default. I checked the interaction length as only 7.1l0 (CAL) Ignored the solenoid material in this study
