The Future of the US program Pier Oddone Symposium for the 30th anniversary celebration of the US/Japan Agreement on High Energy Physics October 21st, 2010
Drivers for the program • Drivers for the US program are simple and universal: the quest to solve the profound mysteries that surround us • The ability to bring together the teams to solve these mysteries: • The next generation of accelerators • The next generation of detector technology • New simulation, computation and analysis techniques Pier Oddone, 30th Anniversay Japan/US, 2010
The triumphs ………………….. • The present theory is a remarkable intellectual construction • Every particle experiment ever done fits in the framework Pier Oddone, 30th Anniversay Japan/US, 2010
……………. and the mysteries • Mystery one: why are we here? From what we learned we should be a soup of photons!!! • Matter and antimatter annihilation. • We need to violate symmetry! Pier Oddone, 30th Anniversay Japan/US, 2010
Is it quarks? neutrinos? higgses? • The B factories asymmetries in quark sector are too small • Use as substrate to understand the presence of new interactions • Super B – factories in Japan (and Italy?) Pier Oddone, 30th Anniversay Japan/US, 2010
Is it quarks? neutrinos? higgses? • Quark sector also studied at Tevatron and LHCb • Are we starting to see “anomalous” CP violation in Bs decays? • To be followed up with Tevatron extension, LHCb, and Super-B factories Pier Oddone, 30th Anniversay Japan/US, 2010
e “ e ” CP Is P( e) P( e)? Is it neutrinos? • Leptogenesis is an attractive alternative • Requires CP violation in heavy neutrino sector • We are far from understanding neutrinos, their masses, mixings, and CP violation + e– Matter Detector + e+ – Antimatter Detector – Pier Oddone, 30th Anniversay Japan/US, 2010
Remove Accelerators from Cockroft-Walton though Booster and Booster neutrino. All the green ones including MuCOOL stay Is it neutrinos? Ultimate Goal multi MW beam large detector (a few 100 kton) long distance (> 1,200 km) Project X Neutrino physics Muon physics Kaon physics Nuclear physics Project X Neutrino physics Muon physics Kaon physics Nuclear physics Project X provides: neutrinos muons kaons nuclei “simultaneously” 2 MW (60-120 GeV) 1300 km Pier Oddone, 30th Anniversay Japan/US, 2010

More surprises in neutrinos ? Pier Oddone, 30th Anniversay Japan/US, 2010
Is it neutrinos? • The attack on neutrino parameters is broad: • Fermilab (MINOS, MINERvA, MiniBooNE and MicroBooNE, NOvA, LBNE) and JPARC beams (T2K, HyperK): different baselines, different energies • Reactor experiments: Double Chooz and Daya Bay • Neutrino-less double B decay: Majorana and EXO • New technologies: scale up of liquid argon TPCs to many kilotons • R&D on neutrino factory Pier Oddone, 30th Anniversay Japan/US, 2010
Or from higgses? • From decays of Higgs at future lepton colliders discover a new source of CP violation (e.g. angular correlations to specific decays) • Solves the mystery of why matter dominates over antimatter Pier Oddone, 30th Anniversay Japan/US, 2010
……………. and the mysteries • Mystery two: what gives mass to elementary particles? • Mass of composite particles understood E=mc2. • But the theory has zero masses for quarks and leptons. What breaks the symmetry? Pier Oddone, 30th Anniversay Japan/US, 2010
……………. and the mysteries • Mystery three: are there extra dimensions of space as string theories require to make sense of gravity ? • Mystery four: are there new symmetries (such as supersymmetry or SUSY) Pier Oddone, 30th Anniversay Japan/US, 2010

ATLAS muon detectors ATLAS Pier Oddone, 30th Anniversay Japan/US, 2010
Higgs searches For very light Higgs, Tevatron is competitive through 2014 in the principal decay mode to the b-bbar – LHC needs about 30 fb-1 to get results for b-bbar mode Pier Oddone, 30th Anniversay Japan/US, 2010
Biggest decision of the decade ! By far the easiest! A global program ILC Enough or LHC Results CLIC or ILC not enough Muon collider Pier Oddone, 30th Anniversay Japan/US, 2010
……………. and the mysteries • Mystery five: why are there three families of quarks and leptons? • The 18 parameters of the Standard Model: you would not be here without them • The whole issue of flavor and the couplings to what lies beyond is one of the deepest puzzles Pier Oddone, 30th Anniversay Japan/US, 2010
Interplay: LHC Intensity Only handle on the next energy scale nothing Intensity Frontier LHC Determine/verify structure of new physics. Anything beyond? Lots Pier Oddone, 30th Anniversay Japan/US, 2010

……………. and the mysteries • Mystery six: what is dark matter • It is everywhere, it is five times more abundant than matter. • We have strong suspicions of what it is Galaxies are spinning too fast to be held together by gravity of the stars Pier Oddone, 30th Anniversay Japan/US, 2010
The search for dark matter COUPP COUPP (2010) CDMS Pier Oddone, 30th Anniversay Japan/US, 2010
The search for dark matter • Next generation prototypes with noble liquids: 1) depleted liquid argon and 2) xenon • However, most of the effort is going to the detection of WIMPS, whereas dark matter could be quite different: axions at one end or super-massive particles at the other • For direct detection eventually scale one or two technologies to the ton scale CDMS Pier Oddone, 30th Anniversay Japan/US, 2010
……………. and the mysteries • Mystery seven: what is dark energy? Not a clue! • Accelerates the expansion of the Universe! • Contains three times more energy than dark matter. Pier Oddone, 30th Anniversay Japan/US, 2010
