Physics 2011 and beyond LHC 2011/12 Higgs-Boson: to be or not be the question for 2011/2012 ? 15

LHC potential performance range Goal: 1 fb-1 Energy: 3. 5 Te. V to 4 Te. V To be discussed at the Chamonix workshop in Jan. 2011. Bunch intensity Baseline 1. 2 x 1011 protons, higher possible from injectors. Number of bunches 450 to 930 bunches (75 ns spacing): potential factor 2. Colliding beam sizes Maintain excellent beams from injectors: 50% smaller than nominal Possible to “squeeze” beams further: another 50% gain! Peak luminosities in the range of 6 to 16 x 1032 cm-2 s-1 could be possible. At least 3 times more than what we have seen in 2010! Integrated luminosity between 1 and 3 fb-1 would appear feasible. S. Redaelli, LHC jamboree, 17 -12 -2010 16

Higgs 2011/2012 What do we know today ? q Theory: m. H < 1 Te. V q Present experimental exclusion: m. H > 114. 4 Ge. V (LEP), 158 < m H < 175 Ge. V (Tevatron) q Favoured region (electroweak data consistency of Standard Model): m H < 158 Ge. V 114. 4 -158 Ge. V is the “hottest” region (although higher masses cannot be excluded) Expected Higgs mass coverage (Ge. V) at LHC Tevatron LHC 10 fb-1 (end 2011) 1 fb-1 7 Te. V 1 fb-1 8 Te. V 95% CL exclusion 114 -185 3 σ evidence ~115, 150 -180 5 σ discovery --- 123 -550 130 -450 152 -174 120 -570 127 -500 150 -176 LHC 2. 5 fb-1 8 Te. V 114 -600 123 -530 138 -220 LHC 5 fb-1 8 Te. V ≥ 114 120 -570 LHC means ATLAS and CMS combined (very preliminary) January 2011

Higgs 2011/2012 If the Higgs is not there LHC needs ~2. 5 fb-1 for exclusion down to lowest masses If the Higgs exists: q Need ~5 fb-1 for 3σ evidence around m. H ~ 115 Ge. V, but enough sensitivity at higher masses (above ~ 120 Ge. V) already with 1 -3 fb-1 q Discovery (5σ) over full allowed mass region requires ~10 fb-1 at 8 Te. V LHC means ATLAS and CMS combined (very preliminary) Note on 8 Te. V vs 7 Te. V: -- same reach with ~20% less luminosity -- for same luminosity, extend low-mass reach down by ~ 3 Ge. V

All the time CERN’s academic environment, our openness & global visibility has a strong tradition and is taken for granted… …but this makes us also an attractive target! Attacks against CERN computers in 2010 have had negative impact on our reputation and on the operation of experiments. It is the responsibility of all of us to protect CERN computing: ► laptops, computers, … ► passwords, web pages, data files, software, … ► computing services, control & DAQ systems, GRID nodes, … Also: respect copyrights of music, videos, etc. Don’t share !!! Let us help you: http: //cern. ch/Computer. Security

2010 Two examples of Upgrades and New Projects

Progress with the Linac 4 Project: Building completion in October 2010 25

Linear Collider Detector project @ CERN LCD: addressing physics and detectors at CLIC and ILC Current focus: Preparation of conceptual design report for CLIC detectors => developed into a truly international effort in 2010 Affiliation of CLIC CDR editors Experimental issues for a CLIC experiment now well understood, and detector geometries for the CLIC benchmark studies were fixed Beam test with a tungstenbased HCAL for linear collider, CALICE collaboration http: //lcd. web. cern. ch/LCD/ 06. 01. 2011

2011/2012 - CDR of CLIC 2011 LC-Project at CERN - TDR of ILC 2012 - CDR of LHe. C 2011 Well in time for the update of the European Strategy for Particle Physics in 2012 Need to position CERN for a global project

2011/2012 Need to position CERN for a global project R&D and Studies ongoing for High Luminosity LHC Linear Collider Project CERN as the laboratory at the energy frontier High Energy LHC LHe. C Neutrino Physics steps towards a more global laboratory consolidate infrastructure improve services for personnel

Opening the door… 2010 Council opened the door to greater integration in particle physics when it unanimously adopted the recommendations to examine the role of CERN in the light of increasing globalization in particle physics. The key points agreed by Council include: – All states shall be eligible for Membership, irrespective of their geographical location; – A new Associate Membership status has been introduced to allow non. Member States to establish or intensify their institutional links with CERN; – Participation of CERN in global projects wherever sited. Romania is Candidate for Accession to Membership since 2010. Negotiations with Cyprus, Israel, Serbia, Slovenia and Turkey applying for Membership are starting. Brazil is applying for Associate Membership.

2010 Improved Services for CERN Personnel Extension of Restaurant 1 Renovation of Restaurants 2 and 3 Online booking of hostels Regular shuttle services (on site as well as to and from the airport) Consolidation of the general infrastructure started. . .

2011 Improving Services for CERN Personnel -Consolidation of the general infrastructure including replacement of surface treatment building -Cheap accomodation in St. Genis -New caterer for Restaurants 2 and 3 -Inauguration of extension to building 40 -Car sharing project open to entire CERN community -New private childcare in St. Genis offering more flexibility and also short term “drop in” day care (starting end of the year). . .

HR strategy implementation 2010 - Code of Conduct – completed on schedule with broad agreement in-house, very well received by Member States; allows Management to take appropriate action when needed - Ombuds Office to handle conflictual situations - New recruitment office enhancing CERN’s visibility and attractivity on the employment markets; visible first results with record breaking applications……

HR strategy implementation 2011 - Implementation of Competency Model in the fields of recruitment, IC award and performance appraisal - Consolidation and continued transformation of HR Strategy - Establish Diversity Office

5 YR and CHIS 2010 Successful execution of the 5 Yearly. Review for implementation in January 2011: increase of the salary grid in 2 stages for CP D-G despite the difficult economic and social situation in the Member States – strictly applying the methodology foreseen in Annex A 1 of the staff rules and regulations Consolidation of the CERN Health Insurance Scheme (CHIS) you can help here since CHIS is YOUR HIS guaranteed through your contributions and through the CERN budget

Pension Fund 2010/2011 First set of measures adopted for implementation in January 2011 to consolidate the CERN Pension Fund: capital injection of 60 MCHF/a until full funding reached increase of contribution rate temporary “freeze” of pensions Second set of measures concerning future recruits and future pensioners under discussion for implementation in January 2012 Both sets of measures are coupled together

Budget 2011 and beyond CERN is attractive CERN is in the spotlight …. but this doesn’t guarantee a budget economical and financial situation in member states difficult, nonetheless Budget 2011 incl. personnel CVI (0. 33%) approved by Council after many bi- and multi-lateral discussions despite the difficult situation in the Member States showing confidence in CERN However continued concern for the next years

Budget 2012 and beyond Need to be even more proactive in promoting CERN’s achievements/possibilities in all areas (research, technology, education, training, . . . ) Use the fact that CERN is attractive and in the spotlight as an opportunity to promote basic science per se basic science as a driver for innovation Increasing importance of KTT Industry Advisor appointed CERN is invited to participate in two sessions of this year’s meeting of the World Economic Forum in Davos recognition of the value of basic science to society ? We will see……but also act

Science and Arts Although we are enjoying unprecedented levels of popular and political support around the world, the trend is still against basic science. This means for us first of all to deliver on our scientific promises. But we also have to show our relevance to society on other levels, and engagement with culture plays an important part. The growing attention and interest from artists, architects, writers, etc allows us to engage with culture in a broader sense. We are engaged in a number of “arts” projects, to be realised only if external funding can be found

Summary 2010 was a memorable year for CERN Physics CERN ‘Opening’ Start of Pension Fund consolidation January 2011

Outlook • Look forward to exciting physics (not only at the LHC) in 2011/2012 Higgs-Boson: to be or not to be ? ? lay the foundations for LHC upgrades and post-LHC era • Requires continued level of commitment and support from member states and partners around the world • Builds on YOUR continued commitment and dedication I am excited and confident January 2011
