Measurement for IMC 2013 • W/Z Measurement: • • Standard for international masterclasses Find W+/W-, Z mass, lepton universality. “Discover” J/Y and U. 3 x [H ZZ* 4 lepton] candidates • • • Repeated in data so each 100 events has one Students look for ZZ signatures; plot on same mass plot. Find a “Higgs hint” at 120 -130 Ge. V. IPPOG Masterclass Steering Group 4 April 2012

Combination of Results: Improvements • New: • From students to tutors to moderators – one spreadsheet • Result: • Smooth data transfer; moderator job simpler • Expressions of satisfaction with improvement • Issues: • Interference – need to lock out? • Edit. Grid glitches require vigilance, maintenance. IPPOG Masterclass Steering Group 4 April 2012
