DESCRIPTION:Speakers: Maiken Pedersen (University of Oslo)\nSharing ATLAS 
 data and research with young students\nMaiken Pedersen\, Farid Ould-Saada\
 , on behalf of the ATLAS Collaboration and IPPOG International Masterclass
 es\n\nIn recent years the International Masterclasses (IMC) featured the u
 se of real experimental data as produced by the LHC and collected by the d
 etectors. We present ATLAS-based educational material using these data all
 owing high-school students to learn about properties of known particles an
 d search for new phenomena. The ambition to bring to the “classrooms” 
 important LHC discoveries is realised using the recent discovery of the Hi
 ggs boson. About 10% of the ATLAS discovery data are made available for st
 udents to search for the Higgs boson: 2fb-1 at 8 TeV for the Z-path\, and 
 1 fb-1 at 7 TeV for the Wpath\, in the 2014 version of IMC. The Higgs stud
 y samples constitute one third of the total sample including Z\, W and oth
 er low mass resonances.\n\nThe goal of the Zpath measurement is to rely on
  the invariant mass concept to identify and measure properties of known pa
 rticles\, such as the Z boson\, inferred from the decay products\, pairs o
 f leptons. When a heavy gauge boson Z´ with mass 1 TeV is mixed with the 
 real data\, the simulated signal shows up in the di-lepton mass distributi
 on\, to the surprise of students\, who realize that they have mastered a d
 iscovery tool. They go on and apply the same technique to di-photons and p
 airs of di-leptons to search for the Higgs boson. To help the buildup and 
 display of the invariant mass distributions\, we developed OPloT\, a scala
 ble\, php-based web-plotting tool for submission and automatic combination
  of all measurements performed. This allows for prompt access of results f
 or further discussion within institutes and during videoconferences. The W
 -Path deals\, with the structure of the proton\, by comparing the numbers 
 of W+ and W-\, and search for the Higgs into a pair of W bosons\, by measu
 ring the angle between the leptons stemming from the W bosons. Event-displ
 ay files are read using Hypathia (Zpath) or Minerva (Wpath). \n\nThe educa
 tional material is tuned and expanded to follow LHC “heartbeats”. In t
 he future we hope to bring new discoveries to the public. Among new featur
 es being implemented in the Zpath\, a signal of graviton resonances in di-
 lepton\, di-photon mass distributions\, and the exploiting of missing tran
 sverse energy to study di-lepton invariant mass endpoints of supersymmetri
 c particles. Finally\, a script is available for more advanced university 
 students to loop through all events.\n\nhttps://indico.ific.uv.es/event/20
