The next ten years: chaos or illumination
Pier Oddone, FermilabBrookhaven Forum 2010
May 28, 2010
Hold on to your seats……..
• The next decade is here! The greatest expectations in generations and the greatest uncertainties....
• As we have heard in BF2010: any number of models are possible – few clues from present experiments.
• The LHC will be the dominant tool – but critical questions remain in other areas: for neutrinos, rare processes, dark matter and dark energy
P. Oddone, Brookhaven Forum, May 28,20102
New physics: what clues do we have?
• The biggies:
Dark matter Dark energy Neutrino masses Matter antimatter asymmetry in the universe Three flavors Unitarity at TeV scale?
• But is the new physics around the corner? Looking through precision tests…….
P. Oddone, Brookhaven Forum, May 28,20103
What clues do we have?
• G-2: anomalous magnetic moment of the muon shows a 3 sigma deviation from SM predictions

Powerful detectors
P. Oddone, Brookhaven Forum, May 28,201014
(See Erbacher and Heinemann at BF2010)
Huge physics reach
• Theorists have imagined a veritable Jurassic Park of possibilities in this new energy range:
Minimal Supersymmetric (MSSM) Many other models of supersymmetry (less
predictive ) New Z’ similar to the Z boson, but higher masses Extra dimensions and Kalusa-Klein towers Technicolor Lepto-quarks Mini black holes ……………………

Detectors are fantastic!
• Physics will come quickly: weeks to months after data taking
• Also means many effects will appear first at the 3 sigma level so we will be chasing many things on the way to discovery
• When will we be able to be confident enough to say what the next machine is?
• Great confusion? (See Lykken at BF2010)

If we need higher energies…..
• If the energy of the ILC is too small (0.5 TeV or a little higher) we will need another approach: CLIC or muon collider
P. Oddone, Brookhaven Forum, May 28,201020
Muon Collider approach
• If the energy of the ILC is too small (0.5 TeV or a little higher) we will need another approach: CLIC or muon collider
• Collider based on a secondary beam: we have experience basing colliders on antiprotons. For muons we must do it in 20 msec.
• The biggest advantages are: narrow energy spread (no beamstrahlung) and small physical footprint (no synchrotron radiation
• DOE OHEP has asked Fermilab to organized the national R&D program

Intensity Frontier
Only handle on the next energy scale
Determine/verifystructure of new physics. Anything beyond?
Intensity is key for neutrinos
• Only weak interactions: very small cross sections >> hard to study
• Need large flux of particles and massive detectors
• Complementary to LHC: measure neutrino parameters (new symmetries?), neutrino masses, matter-antimatter symmetry violation and surprises.
• This route like the energy path depends of what we find in the current generation of experiments

• ATLAS/CMS discovers strongly coupled SUSY
• A host of new particles: fit roughly some masses, make assumption on couplings

At the intensity frontier: Super B
• One hundred times the luminosity of existing B-factories.
• Complementary program to LHC: flavor physics will manifest discoveries at LHC as well as higher mass scales
• Unlikely to be produced with present designs due to huge power loads: go to low emittances and waist focus. The main challenge is to maintain the low emittance. Two designs one in Japan and one in Italy

waist is orthogonal to the bunch axis
waist moves to the axis of other beam
With crabbed waist, all particles from both beams collide in the
minimum by region, producing a net gain in luminosityand a broad tune plane

Three main thrusts
• The energy frontier: produce particles at highest energy
• The intensity frontier: the most particles for neutrinos and rare decays
• Cosmic frontier: study phenomena in nature
