  3. UED A g-2 example: SUSY SUSY Extra Dimensions The future am measurement could separate the two models by more than 7 standard deviations and thus allow for a clear decision in favor of one of them The quest for new physics understanding requires different tools • LHC: direct search for new particles • But, what new physics will they reveal? Mostly Nuclear Physics • Precision measurements: • Lepton flavor violation • EDMs of e, n, atoms, etc. • 0nbb • Muon g-2 Rare • Weak mixing angle • p, K and B decays • Unitarity tests Consider a post-LHC world with many new mass states found

  4. Projects Worldwide … • Muons • Lifetime – GF • 3 Expts: MuLan, FAST, RAL • Decay parameters • Michel – TWIST r, d, h, Pmx • Transverse polarization (h) - PSI • Anomalous magnetic moment (g-2) • New proposal @ FNAL • Lepton Flavor Violation • meg – MEG at PSI • me conversion – mAeA – Mu2e at FNAL • EDM – • E821 PRD submitted ~10-19 ecm • Lorentz / CPT violation test – • E821 PRL submitted; e.g., precession vs. sidereal day • Muonic Lamb shift – in progress (QED) • Pions • Lepton universality: • p en – PEN • p en – PIENU

  5. Projects Worldwide … • Polarized Electrons • sin2qW – ep – QWEAK at JLab • sin2qW – ee Møller at 11 GeV JLab • sin2qW – PVDIS at 11 GeV JLab • Tau leptons • Lepton Flavor Violation • (50 modes) – Belle & BaBar • Lepton universality in many tau decay modes • Nuclei • 0vbb Decay • Majorana “Demonstrator” 60 kg Ge • CUORE – 200 kg 130Te • EXO - 136Xe (HEP funded)

  6. Projects Worldwide … • Atoms / Molecules • EDMs • Various systems in many labs • Neutrinos • q13 • Daya Bay • Mass – Katrin • CP • Cross sections • Oscillation parameters improved • Solar • Geothermal • … lots… • DARK Matter (!)  interesting connection to the pN S term through the cross section sensitivity to the strangeness content of the nucleon • Direct detection sensitivity depends strongly on this value; c.f. K. Olive • Many efforts • DUSEL on horizon

  7. Projects Worldwide … • Neutrons • Lifetime • NIST – ultracold lifetime • Ultracold traps • Munich/PSI magneto-gravitational trap • Decay parameters (many efforts) • PERKEO II new results • “big A” UCN-A at LANSCE • “big A” PERKEO-III at ILL • “little a” – aCORN • R (transverse e polarization) at PSI • Electric Dipole Moment • ILL – CryoEDM • FnPB – 3He/4He • PSI – Old ILL with upgrades • ILL-II – Serebrov

  8. Precision Neutron Physics A 100-fold improvement in the neutron EDM dn to < 2 x 10-28 e·cm The Fundamental Neutron Physics Beam at the SNS opens up the possibility for a program of precision neutron physics experiments. Highest among them, is

  9. Neutrino Physics Determine the unknown, and key mixing angle q13 The unique cluster of powerful reactors in Daya Bay, China, nestled near mountain overburden, will permit a next-generation neutrino program with several detectors in a short-baseline configuration, and …  sin22q13 to 0.01 or better

  10. Muon Physics The powerful PSI accelerator – 2.2 mA @ 590 MeV provides intense, low-energy, polarized muon beams. Coupled with the NSF-supported beam kicker, permits: • Muon lifetime • Fermi constant GF • Muon Capture on the proton • Pseudoscalar couplinggP • Muon Capture on the deuteron: • “Calibrating the sun”L1A  

  11. Future Muon Physics The post-Tevatron era at FNAL opens up the use of a network of coupled 8 GeV proton rings, with capabilities for intense, custom beam structures, and parasitic utilization with the neutrino program Next-generation g-2 experiment  0.14 ppm precision Muon to electron conversion BR to < 10-16 in approved phase I

  12. The completed parts of our muon program have had high impact. We expect our neutrino and EDM and future muons efforts will be as important (or more) • BNL E821 g-2 Experiment • Hertzog & Morse, Annual Rev. Nucl. Part. Sci. • > 1500 SPIRES citations to collaboration papers • Arguably strongest hint of SUSY-like new physics (see later) • MuCap at PSI • Resolved > 30-year old difficult determination of gPand its comparison to theory • 2008: Banks and Clayton receive DNP Thesis price • 2008: Kammel invited for review “Precision Muon Capture”in Annual Review of Nuclear and Particle Science • 2008 Kammel elected to APS Fellowship • scientific leadership and development of novel experimental techniques related to muon capture, muon catalyzed fusion and other precision muon and antiproton measurements. • Future prospects • Hertzog, Kammel, Marshall invited for review: “New muon experiments and future prospects for muon physics” in Reports on Progress in Physics
