  1. Graphical representation and animations of CERN physics and technologies Rolf Landua CERN PH-EDU IPPOG Meeting, 4 November 2011

  2. PART 1 : GRAPHICAL REPRESENTATION OF “INVISIBLE” OBJECTS Guide lines Logical and consistent use of ‘metaphors’ for particle properties Appealing appearance - (even) for non-physicists Same representation in 2D- and 3D-graphics Object library for use in future graphics / animations

  3. ....quarks visible or not ....without or with gluons ....without or with sea quarks Example: Many ways to represent a proton how to represent electrons, neutrinos? Strong vs weak, electromagnetic charge? Spin 1/2 vs Spin 1 ?

  4. Spin 1/2 Colour (blue) Weak charge (“up”) Electric charge (+1, pink) New scheme used for animations *** draft version - not quite ready yet *** UP QUARK

  5. Blue colour Red colour Green colour Quark declination in ‘colour’ space

  6. Weak charge (“up”) Electric charge (- cyan) Electric charge (+ pink) Weak charge (“down”) Weak and electric charge UP QUARK: DOWN QUARK

  7. Electric charge - Colour charge 0 Electric charge 0 Colour charge 0 ELEKTRON E-NEUTRINO Quarks versus Leptons UP DOWN

  8. Three families of leptons T-NEUTRINO E-NEUTRINO M-NEUTRINO ELEKTRON MUON TAU 1 1I I1I

  9. Anti-Quarks obtain by ‘hue inversion’ Red Anti-red UP ANTI-UP DOWN ANTI-DOWN

  10. POSITRON E-ANTINEUTRINO Anti-Leptons E-NEUTRINO ELEKTRON

  11. Spin 1 M = 0 Field particles: PHOTON Electric charge 0 Colour charge 0

  12. massive W- Zo W+ Electric charge - Electric charge - Electric charge + Field particles: ELECTROWEAK Photon massless

  13. Field particles: GLUONS Colour charge: Red - Antiblue Spin 1 M = 0

  14. All gluon colour combinations

  15. Spin 0 .... finally, the (elusive) HIGGS Electric charge 0 Colour charge 0 massive

  16. COMPOSED OBJECTS - THE PROTON

  17. PROTON: ANIMATION *** Low resolution version ***

  18. Goals Composition (communication, education, ATLAS, CMS) D. Barney S. de Gennaro D. Dominguez S. Goldfarb R. Landua C. Marcelloni L. McCarthy J. Pequenao C. Pralavorio Produce a consistent set of (3D) animations needed for - press office / media - new CERN movie for visits service - visit point project and exhibitions PART 2 - CERN WORKING GROUP ON ANIMATIONS

  19. Topics ranked according to priority • 1) Matter and forces • the main components (u,d,e,v) • forces: strong, electromagnetic, weak • how to build protons/neutrons/nuclei; atoms; transforming particles • heavy quarks, leptons; Higgs • 2) The Higgs mechanism • 3) Producing a Higgs particle in a p-p collision • 4) How an LHC experiment ‘sees’ invisible particles • Higgs • Missing energy/momentum (‘SUSY, extra dimensions, etc’) • 5) Evolution of the Universe • Matter-Antimatter (a)symmetry • Quark-Gluon Plasma • Nucleon formation • Nucleosynthesis • Recombination and CMB • Star and galaxy formation - role of dark matter

  20. Topics ranked according to priority (2) 6) “Virtual tour of the CERN accelerator network” 7) “The World-wide LHC GRID - what it is, how it works” 8) “Computing - from the experiments to the discovery of new phenomena” 9) “How the LHC works - the main components and their function” OTHER TOPICS (priority to be defined) Matter-Antimatter asymmetry in Bd decay Energy becomes mass - particles and antiparticles at CERN Extra dimensions and black holes Dark Matter - how we know it is there, how to find it at CERN Supersymmetry: what is - and why we think we need it Particle detectors - how they work, how they are used (Si strips, pixels, tracking; calorimeters; RPC, drift tube, CSC, alignment/calibration) Gauge symmetries and heavy bosons (old and new), Z’ Compositeness (preons) Technicolor (composite Higgs, techni-particles) 4th Generation

  21. ANIMATION GROUP : Work flow PHASE 1 - DEVELOPMENT: Conceptualization (brainstorming), script PHASE 2 - PRE-PRODUCTION : Story board, animatic (rough animated version), design chart PHASE 3 - PRODUCTION: Modeling, materials, shaders, textures; layouts, animations, lighting PHASE 4 - POST-PRODUCTION: Final rendering, compositing (layers), editing, sound, credits

  22. ANIMATION GROUP : Work flow (example) Structure of matter (part 1: conceptualization)

  23. Story board (beginning ...)

  24. That’s all for now ... watch this space.
