2. ATLAS O&E 2/2014Uta Bilow, TU Dresden2 Concept of IMC High school students (15 – 19) are „scientists for one day“ Get invited to a research institute or university Introductory talks (standard model, detectors, accelerators) 2 h measurement with LHC data International video conference (3 – 5 inst. + CERN/Fermilab)

4. ATLAS O&E 2/2014Uta Bilow, TU Dresden4 Measurements ATLAS W-Path (TU Dresden) MINERVA W charge asymmetry  structure of the proton 6.000 *real data* preselected events (900 W  ℓn ) different set of data for each institute, combined in the VC H  WW  search for Higgs 693 WW candidate events measure opening angle between 2 leptons, combine results in histogram (angular distribution) ATLAS Z-Path (Univ. Oslo) HYPATIA Find Dilepton events  calculate invariant mass 20 000 *real data* preselected events (Z  ℓℓ, J/Psi, Y; 2000 *simulated* Z´  ℓℓ  search for yet undiscovered mass spectrum: Search for Higgs: H  ZZ  ℓℓℓℓ (40 events) H  γγ (12 000 events)
