Martin Pohl High energy • LHC and ATLAS – – – – – Impressive performance: collider, experiment, computing Detector well understood: jets, leptons, missing energy Analysis closely follows data taking, 3 -4 thesis per year Top physics: SM but not so standard Papers 50% on searches: SUSY, WIMPs and exotics not found up to ~Te. V range (but would have been if they existed!) Higgs WW, ZZ, γγ: M < 135 Ge. V, new results for ICHEP If Higgs exists: measure properties/couplings, regularization of VV scattering If light Higgs does not exists: what keeps VV scattering finite? Extend mass range by high luminosity 30%/3000 fb-1 • Upgrades – Phase 0: IBL – Phase 1: pile-up ~50, MUCH, LV 1 calo trigger, FTK, AFP 2018 – Phase 2: new inner detector, pixel, short+long strips 2021/22 DEPARTEMENT DE PHYSIQUE NUCLEAIRE ET CORPUSCULAIRE Page 2

Martin Pohl ATLAS@LHC DPNC: IBL AFP, FTK? ? or LEP 3 or CLIC? DEPARTEMENT DE PHYSIQUE NUCLEAIRE ET CORPUSCULAIRE Page 3

Martin Pohl High precision FAST • Current experiment: – – – Muon lifetime FAST@PSI Final results this summer • Future project: – Lepton flavor violation – MU 3 E@PSI DEPARTEMENT DE PHYSIQUE NUCLEAIRE ET CORPUSCULAIRE Page 4

Martin Pohl Neutrinos • Oscillations probe obscure sector of SM: flavor – Neutrinos have mass and they oscillate, νe disappear from νe beam and appear in νμ beam, ντ appear in νμ beam – Attention: total cross section a few fb! Single events! – T 2 K is leading long baseline experiment, final statistics in 2020 – Maki-Nakagawa-Sakata matrix in leptonic weak charged current! – Θ 13 large, good news for mass hierarchy; Θ 23 not maximal? – « Normal » or « inverted » hierarchy? Mass scale? – Dirac or Majorana or both? Sterile heavy νR, anti-νL? CP violation? • Future beams and experiments: – – – Daya Bay II (20 kt) Pingu for Ice. Cube, cheap and quick option? CN 2 PY + LAGUNA/LBNO (20 kt)? INO (50 kt), Hyper-K (1 Mt), LBNE, NF 2 PY CP phase not for tomorrow! DEPARTEMENT DE PHYSIQUE NUCLEAIRE ET CORPUSCULAIRE Page 5

Martin Pohl CAP Genève Space Projects • Data taking phase: • Integral: data center at ISDC ESA • AMS on ISS: large Uni. Ge contribution NASA • Planck: no Swiss hardware, analysis ESA • Construction phase: • POLAR: GRB polarimeter for Tiangong 2, CAP + PSI GESSA • ASTRO-H: filter wheel mechanism, CAP + RUAG JAXA • Assessment and definition phase: • EUCLID: selected M 2, shutter design ISDC ESA • JEM-EUSO on ISS: LIDAR actuator JAXA • LOFT: M 3 candidate, Large Area Detector, CAP + CSEM ESA • DAMPE GESSA • Conceptual design phase: • HERD (next step beyond AMS and FERMI) GESSA All phases, all major players DEPARTEMENT DE PHYSIQUE NUCLEAIRE ET CORPUSCULAIRE Page 6

Martin Pohl Ground-based and underground AP expt’s • Data taking phase: • • • Ice. Cube: atmospheric astrophysical cosmological neutrinos Flares and point sources: new results soon Upgrades: Pingu, ARA • Multi-messenger astrophysics: • Promissing paradigm: attack sources by all means (γ, CR, ν, gravitational waves) • Photons of multiple wavelengths: Source properties, acceleration mechanisms • Photons, neutrinos: Source properties, leptonic vs hadronic • Preparatory phase: • Cherenkov Telescope Array, ATLAS-size project, wide physics scope • FACT camera prototype (with ETHZ) • Uni. Ge proposal: Davis-Cotton SST with FACT-type camera DEPARTEMENT DE PHYSIQUE NUCLEAIRE ET CORPUSCULAIRE Page 7

Martin Pohl General observations • I share the excitement about initial LHC and ATLAS performance and results. • I do not share the premature disappointment with the lack of immediate spectacular discoveries. • We have only scratched the surface of LHC physics! • The « weight » of different pillars inside particle physics in « public opinion » is subject to large short term shifts. • Do not listen to this, our time scale is 10 y! • There is no more grace period for esperiments, where statistical error hides systematics. Its all about systematics, stupid! • In general, our Road Map is still right! We can continue to use it to orient us. DEPARTEMENT DE PHYSIQUE NUCLEAIRE ET CORPUSCULAIRE Page 8

Martin Pohl Conclusions • DPNC is: – – – Innovative power in detector design, construction and data analysis; Perseverance in getting at the physics; Proliferation of projects for the future. • My opinion: we should not reduce our ambitions easily! • How can we live up to our ambitions? – – We need a perspective for growth in personnel. We need to maintain and develop technical groups and their skills. NCCR Universe will give this perspective, if approved. In addition we need investment funds comparable to the initial ATLAS investment. Existing sources are insufficient. – We must use all imaginable sources: local, federal, European. • If we want any or all of this to be successful, we need the general public to support us. Reach out! DEPARTEMENT DE PHYSIQUE NUCLEAIRE ET CORPUSCULAIRE Page 9
