ttt International Masterclasses with ATLAS data ATLAS outreach meeting, CERN, Uta Bilow, TU Dresden

International Masterclasses - the idea Concept Students (16-19 year-olds) spend 1 day at research institute Listen to scientists‘ introduction to particle physics Work like and with scientists („masters“): measurements with real particle physics data Basic idea from UK (1996, Roger Barlow et al.) Objectives Let students explore fundamental forces and building blocks of nature Demonstrate the scientific research process Stimulate interest in science (proven in refereed evaluation Physics Education 42 (2007) ) Offer opportunity for authentic experience ttt

IPPOG International Masterclasses Create an international collaboration of students over 130 institutes from 24 countries hold masterclasses parallel programme in U.S. organized by QuarkNet more than 8000 students participating since 2005: ~3 weeks each year in March 5 masterclasses join in video conference with CERN at the end of the day discuss results and differences combine results (better accuracy) quiz and prizes questions to scientists at CERN schedule, physics framework, description of all participating institutes: ttt

Participation International Masterclasses In 2012: + Kroatia + Ireland US (Quarknet) adding: - Canada - Columbia - China - Japan ttt

New in 2011: LHC in Masterclasses ATLAS W-Path (K.Jende, M.Kobel et al., TU Dresden) ATLAS Z-Path (F.Ould-Saada, M.Pedersen, Oslo Univ) CMS (K.Cecire et al.): J/Ψ reconstruction, in 2012: W/Z measurement with real CMS data ALICE (D. Hatzifotiadou et al.): looking for strange particles Positive feedback from organisers and students „students liked it very much“ „big success“ „students enjoyed the new exercises“ „I had the great feeling of having worked with real data like a scientist“ ttt 48 MCs 32 MCs 26 MCs 10 MCs

ATLAS W-Path 995 *real data* preselected events (~ 200 W  ℓ ) W charge asymmetry  structure of the proton 5 *simulated* H  WW  search for yet undiscovered Simplified interpretation: Expected raw student measurement: #W + /#W - = 1.56 ± 0.17 Compare to first ATLAS paper: #W + /#W - = 1.52 ± 0.07 CERN-PH-EP– (October 2010) 44% 22% 61% 39% Using MINERVA ttt

700 *real data* preselected events (~ 300 Z  ℓℓ ) Find Dilepton events  calculate invariant mass 300 *simulated* Z´  ℓℓ  search for yet undiscovered Derive mass spectrum Discuss importance of invariant mass concept Discuss meaning of finite width Discuss meaning of new mass peaks (Z´, not shown above) Using HYPATIA ttt ATLAS Z-Path

Use of real data one of the key elements of all programs! What kind of data do you prefer to work with? (survey K.Jende, 425 students answered) ATLAS policy: published data good data quality caveat on the DVD: for educational purposes only Real data! ttt

Plans for 2012 W-path: *real data* preselected events (~ 2000 W  ℓn )  give each institute a different set of data, which can be compared for consistency and combined in the video conference. include 250 events WW + 0 jets  students measure opening angle between 2 leptons and combine their results in histogram for angular distribution Z-path: larger data sample use automatic tools to loop through under development, for 2013? ttt

International Masterclasses setup All frameworks (ATLAS, CMS, ALICE…) collected by IPPOG at Translation via IPPOG group  Available in 4 (ALICE) to 11 (ATLAS) languages Descriptions for local organizers at n&page=exercises n&page=exercises Central Organisation: TU Dresden (M. Kobel, U.B.) 10 ttt

Refereed evaluation in Physics Education 42 (2007) severity: just right success independent of a-priori knowledge and gender 15

Most important correlation Understanding the scientific research process generates interest in (especially modern) physics 16

Other Big Programs using real LHC data masterclass – like UK National Particle Physics Masterclasses at 19 institutes, events / year (mostly March/April) German „Netzwerk Teilchenwelt“ (Dresden et al.) (masterclasses, cosmic rays and more) 22 institutes send Ph.D. students to schools ( /year) Funded w/ 0.35M€/year over 3 years by German Ministry of R&E other formats Interactions in Understanding the Universe I2U2 (FNAL et al.) Among it: CMS E-lab: www18.i2u2.org/elab/cms/home/project.jspwww18.i2u2.org/elab/cms/home/project.jsp student-led, teacher-guided online project in the class-room Funded w/ 0.48M€/year over 3 years by NSF Learning with (Athens et al. : finished) and develop frameworks and educational resources for teachers and students Funded w/ 0.30M€/year over 2 years by European FP7
