FIRST YEAR OF DISCOVERY

1. Peter Hansen FIRST YEAR OF DISCOVERY Peter Hansen DG presentation

2. Threethemes • New physics (ATLAS) Understand the electro-weaksymmetry breakdown. Find ”new physics” , including the source of ”dark matter”. • Quantum Chromo Dynamics (ALICE and ATLAS) Understand precisely the consequences of QCD. Both as background for new physics and in itsown right, including the quark-gluon plasma state of the earlyuniverse. • The earliest of structures (PLANCK) Obtain information about the universe at the largest of scales. In all three themes, theory is essential! Peter Hansen DG presentation

3. New Physics searches • Three 2010 publications lead by Discovery members: 1) Di-jet angular distributions and contact interactions. 2) New limits on Stable Massive Particles (project 4) 3) New limits on dark matter annihilation (project 13) About 20 conference contributions. In this work the collaboration with theory was essential! Note also that 1) is an ATLAS publication 2) is mixed theory experiment and 3) is from the Discovery Planck group. Things are deeply connected! Peter Hansen DG presentation

4. Electro-weak physics • First publications on W,Z and top quark production at 7 TeV. Agrees with Standard Model (project 3, but more statistics needed). • LHC is running so well that it may be possible to exclude (or find) the Higgs in 2011-12. Requires immense statistics. (project 4). Decision whether or not to delay the 2012 shutdown to be taken in February. Peter Hansen DG presentation

5. Attacking QCD from all sides What we need to calculate: What we measure: • hard process amplitudes, • incoming parton densities, • underlying event, • transport in quark-gluon matter • hadronization Peter Hansen DG presentation

6. Strong pp interactions @ 7 TeV • 60 pub+conf on ATLAS and ALICE detector performance.Performance is fantastic !- still a lot to do, however (projects 1 and 2). • 30 pub+conf on “soft QCD”. Many surprises here: Unexpected number of particles and new phenomena. (projects 10 and 6) • Remarkable publications on new string theory techniques for QCD amplitudes. (project 9) • First Neural Net determination of parton densities (project 7 based on HERA data, next year the added information from LHC will be considered). Peter Hansen DG presentation

7. The “little big bang” • Seamless Pb+Pb run in November/December. • ALICE published particle multiplicities (project 10) cleaning out in the forest of predictions: Peter Hansen DG presentation

8. The “little big bang” • ATLAS published evidence for jet quenching , confirming the existence of the Quark-Gluon Plasma (project 11). Peter Hansen DG presentation

9. PLANCK surveyed the micro-wave sky More than 550 days of observation with unprecedented precision. The angular precision will be even better than anticipated, due to launch. A very wide band of frequencies, 30-857 GHz, is explored. First analysis will focus on large-scale point sources (galaxy clusters). From 2012 the cosmic contribution to the micro-waves will be released. Peter Hansen DG presentation

10. Discovery CMB plans for 2011 • Next year we will participate vigorously in the analysis of the sources such as this new super galaxy cluster. Planck will produce a map of 40000 such clusters which contain very interesting information on dark matter. • We have discovered an exiting parity asymmetry in the previous WMAP data. This will be pursued with the cosmological Planck data. But meanwhile all possible explanations will be tried out. Peter Hansen DG presentation

11. Discovery population Includes PhD-student guests and professor emeriti. Assumes current funding, professor and master all years (optimistic). The profile resonates well with the LHC/Planck schedule. Peter Hansen DG presentation

12. Discovery offices ALICE Includes lab-space 60m2, Meeting rooms 60m2, Shared auditoriums, Server rooms, workshop 4 Kitchens/coffee rooms, 4 large offices at CERN ATLAS+IT PLANCK THEORY+NBIA Peter Hansen DG presentation

13. Discovery Funding • Primary funding: Danish Foundation for Basic Research • Thanks! • Danish Research Councils: Grant for experiments at CERN • Danish Research Councils: 5 year “Women head of research” to StefaniaXella • Danish Research Councils: Personal grant to Simon Badger • Danish Research Councils: Personal grant to EsbenKlinkby • Lundbeck: 5 year center grant to Troels Petersen • NBIA: 5 year grant to Niels Emil J. Bjerrum-Bohr • KU: Salaries to all the professors + 3 PhD students++ Peter Hansen DG presentation

14. Hosting guests • The center enables inviting guest researchers. This is extremely beneficial! • In 2010, 29 visitors spent from 6 months to a day at the center. (The most-well-known: Tim Berners-Lee!). • In 2011, a similar number of visitors are planned. • Allguests have brought their own salary. Peter Hansen DG presentation

15. The Events • Inauguration and international workshop, January • LHC 7 TeV press event, March • MC4BSM, April • Discovery Spring Meeting, May • Cosmology & astroparticle workshop, June • Copenhagen ATLAS Week, July • Cosmology theory vs exp workshop, August • Big Bang Exhibition, Sept 2010-Jan 2011 • Chris Quigg visits, October • PhD Course on Advanced Simulation Techniques, November • Igor Novikov 75, November. Dines Hansen 70, December. • Discovery internat in Vedbæk, December. Planning for next year. • COMING UP NEXT: Workshop on hadron production in pp and PbPb in March A firework of activity! Peter Hansen DG presentation

16. Outreach and communication • 4 press releases, all giving television spots etc • Hands-on-CERN, both the international and local events. • Many (like 20) talks at public courses. • Big Bang Exhibition, Experimentarium Sept-Jan • Preceeded by PLANCK exhibition at Frederiksbergsrådhus • Kulturnat in October at NBI with common Discovery exhibition • Cosmic ray set-up for schools advancing, slowly but surely. • LATEST: Discovery pamphlet available! • and Web page since day 1. Peter Hansen DG presentation

17. DISCOVERY organization

18. International organization The theorygroups have establishedinternational networks for exchangingideas but publishmostlyalone. The twoexperimentalgroupsare parts organizations, eachcomposed of thousands of scientistsaround the globe, withformal obligations as regards to economic and workcontributions for each person. At the bottom of the organizationsare hundreds of workinggroups and task forcesacross institutions. Papers arepublishedin common(103authors).

19. Example of (top level) organization

20. Open Access GREATsubject, since it waspioneered by particlephysics! • In the dark ages therewereonlyexpensive journals. Bad for pooruniversities. • Thenpaperpreprints. Alsoexpensive and biased. • Then SLAC introducedSPIRES, a database of all (particlephysics) papers. In 1991 thisbecame the first WWW site in the US (due to connectionswith Tim Berners-Lee).

21. Open Access • Also in 1991 Paul GinspargintroducedArXiv (sponsored by Los Alamos and nowCornell). Everybodyuploadtheirpapertherefree for anyone to see. With SPIRESyoucanthenseewhere it is published, howmany citations etc. • If you still insistreadingpapers from the journal sites, then CERN has a deal withpublishing houses aboutOpen Access to all CERN-relatedlitterature.

22. Conclusions • The firstyear of the Discovery center has been OK in terms of scientific output and visibility. • We havesomeplans for nextyear, not too clear. • Weare not verygood at”HR”, organization and communication. In short, weare not good at beinghappy. Hope to bebetternextyear.
