Accelerating Science and Innovation CERN Long-Term Plan Glion Colloquium / June 2009 R.-D. Heuer, CERN HiLumi Kick-Off, 18 Nov 2011
Past few decades “Discovery” of Standard Model through synergy of hadron - hadron colliders (e.g. Tevatron) lepton - hadron colliders (HERA) lepton - lepton colliders (e.g. LEP, SLC)
Test of the SM at the Level of Quantum Fluctuations prediction of the range for the Higgs mass indirect determination of the top mass LEP possible due to • precision measurements • known higher order electroweak corrections

‘Today’ Exciting Times At the energy frontier, the LHC brings us into unexplored territory: Excellent progress Accelerator – Experiments – Grid
For most questions: new particles should appear at TeVscale or below territory of the LHC Key Questions of Particle Physics origin of mass/matter or origin of electroweak symmetry breaking unification of forces fundamental symmetry of forces and matter where is antimatter unification of quantum physics and general relativity number of space/time dimensions what is dark matter what is dark energy
Summary of Prospects SM-Higgs Boson, with a mass between (114 - 600 GeV) will either be discovered or excluded until end 2012
LHC and the Standard Model Finding the Higgs: Discovery Excluding the SM-Higgs: Discovery Reminder: LHC is poised to clarify mechanism of electroweak symmetry breaking
Oversimplified Summary of Searches for New Physics
LHC and Theory… Murayama, ICFA Seminar, 2011 CERN
LHC Strategy Full exploitation of the LHC physics potential maximize integrated luminosity useful for physics
The predictable future: LHC Time-line Start of LHC 2009 Run 1: 7 TeV centre of mass energy, luminosity ramping up to few 1033 cm-2 s-1, few fb-1 delivered LHC shut-down to prepare machine for design energy and luminosity 2013/14 Run 2: Ramp up luminosity to design (1034 cm-2 s-1), ~50 to 100 fb-1 Injector and LHC Phase-I upgrades to go to ultimate luminosity 2017 or 18 Run 3: Ramp up luminosity to 2.2 x design, reaching ~100 fb-1 / year accumulate few hundred fb-1 Phase-II: High-luminosity LHC. New focussing magnets and CRAB cavities for very high luminosity with luminosity levelling ~2021/22 Run 4: Collect data until > 3000 fb-1 2030
Key message ‘Tomorrow’ There is a 20 years programme at the energy frontier with the LHC: 7 TeV 14 TeV design luminosity 14 TeV high luminosity (HL-LHC)
Accelerating Science and Innovation clear and exciting prospects for the next two decades for the LHC and CERN at the energy frontier Glion Colloquium / June 2009
Glion Colloquium / June 2009 Accelerating Science and Innovation beyond LHC ? CERN and the energy frontier
Road beyond Standard Model Next decades At the energy frontier through synergy of hadron - hadron colliders (LHC, HE-LHC?) lepton - hadron colliders (LHeC ??) lepton - lepton colliders (LC (ILC or CLIC) ?) (μ-collider ???) LHC results crucial for decisions at the energy frontier

Determining Leptoquark Quantum Numbers • Single production gives access to quantum numbers: • fermion number (below) - spin (decay angular distributions) • - chiral couplings (beam lepton polarisation asymmetry)

Linear Colliders: ILC / CLIC Both projects are global endeavours Wide range of Physics Topics, e.g. Higgs (self) couplings Z, W, Top studies new physics
High Priority Items for Linear Collider Projects ILC and CLIC projects LC project Construction Cost Power Consumption Value Engineering
CERN today….into the future • CLIC conceptual design report by 2012 • Participation in all LC activities • LHeC conceptual design report 2011/early2012 • R&D for high-field magnets (towards HE-LHC) • Generic R&D (high-power SPL, Plasma Acc)
from Choices ? to Choice ! • Update of the European Strategy for Particle Physics in 2012/13 - Several Meetings with international participation bottom-up process: community input requested - Finalization: May/June 2013 • Started with the ICFA Seminar 3-6 October 2011 at CERN Use as 1st step to harmonize globally Particle Physics Strategy
Results from LHC will guide the way We are NOW in a new exciting era of accelerator planning-design-construction-running and need • intensified efforts on R&D and technical design work to enable these decisions • global collaboration and stability on long time scales(don‘t forget: first workshop on LHC was 1984) more coordination and more collaboration required
CERN: opening the door… • Membership for Non-European countries • New Associate Membership defined • Romania in accession to membership • Israel now Associate Member in accession to Membership • Negotiations started with Cyprus, Serbia, Slovenia, and Turkey concerning membership • Several countries expressed interest in Associate Membership • CERN participation in global projects independent of location
In summary • By year 2013, experimental results will be dictating the agenda of the field. • Early discoveries will greatly accelerate the case for the construction of the next facilities (Linear Collider, n-factory, HE-LHC…) • No time to idle: a lot of work has to be done in the meantime
In summary We will need • Flexibility • Coordination • Preparedness • Visionary global policies
...and a bit of luck! Thank you!
