  8. We are doing extremely well! • AIP’s Ten Top Physics Stories for 2007 • Three out of ten are from HEP: • The Energy Frontier: The Tevatron • in its quest to observe the Higgs boson, updated the top quark mass and observed several new types of collision events, such as those in which only a single top quark is made, and those in which a W and Z boson or two Z bosons are made simultaneously. http://www.aip.org/pnu/2007/split/821-1.html • The Intensity Frontier: The MiniBooNE Experiment • solves a neutrino mystery, apparently dismissing the possibility of a fourth species of neutrino.http://www.aip.org/pnu/2007/split/820-1.html • The Cosmic Frontier: The Auger Observatory • Based on data recorded at the Auger Observatory, astronomers conclude that the highest energy cosmic rays come from active galactic nuclei. http://www.aip.org/pnu/2007/split/846-1.html

  9. High Intensity Proton Accelerator: Project X8 GeV ILC-like Linac + Recycler + Main Injector National Project with International Collaboration 8 GeV ILC-like Linac 9mA x 1msec x 5Hz Recycler: 100-200 kW at 8 GeV for precision measuremtns Main Injector: >2 MW at 60-120 GeV for neutrinos

  11. High Intensity Proton Accelerator: Project Xhigh duty factor, high availability, good beam structure Stretcher Possibilities: Accumulator / Debuncher, Recycler, Tevatron 8 GeV ILC-like Linac Recycler: 100-200 kW at 8 GeV for precision measuremtns Main Injector: >2 MW at 60-120 GeV for neutrinos Project X: Naming Contest http://www.fnal.gov/directorate/Longrange/Steering_Public/Name-ProjectX.html

  12. Physics of Flavor • Flavor phenomena • Essential to shaping physics beyond the SM. • SM is incomplete: • Neutrino Masses (flavor) • The only new physics seen so far in the laboratory • Baryon Asymmetry of the Universe (flavor) • Dark Matter • Dark Energy • Inflation

  13. Neutrinos The enigmatic neutrinos are among the most abundant of the particles that make up our universe. To understand the universe, must understand neutrinos. Behavior is so different from other particles. Opening a “new” window

  14. Neutrinos • Neutrino masses • via the See-Saw mechanism, point to new physics at a very high mass scale (unification scale). • Baryon Asymmetry of the Universe • Possible scenarios as the source • Electroweak baryogenesis – LHC and ILC. • Leptogenesis – Neutrino CP violation would support it. • The Four Measurements • value of sin22q13 • Are neutrino masses Dirac or Majorana? • Is the mass ordering normal or inverted? • CP violation

  15. Muons g In SM W- nm ne m- e- x Umi U*ei virtual n mixing • can be real (m eg) or virtual(m + neucleus  e + neucleus) Experimental reach ~ 10-13 (m eg), 10-17 (mN  eN) 3a Dm21i 32p M2W S U*miUei 2 i= 2,3 Br(m  eg) = < 10-54 Neutrinos change from one kind to another. Do charged leptons do, too?

  16. Muons: m to e Conv.(mN  eN) in New Physics Supersymmetry Heavy Neutrinos Compositeness Second Higgs Doublet Leptoquark Heavy Z’ Anomal. Z Coupling MLQ = 3000 (lmdled)1/2 TeV/c2 Lc ~ 3000 TeV rate ~ 10-15 LQ g(Hme) ~ 10-4g(Hmm) |UmNUeN|2 ~ 8x10-13 MZ’ = 3000 TeV/c2

  17. Kaons: Rare Decays Standard Model Br(K+  p+nn) = 8 x 10-11 Br(KL  p0nn) = 3 x 10-11 W W • An almost-Minimal Flavor Violation World • Measuring small deviations from SM is important. • Experimental focus: • Theoretically & experimentally clean – a few % uncertainty • ~1,000 clean Kaon events with Project X

  18. Muons g-2 TeV-based Neutrinos - Electroweak Precision Charms D0 – D0 mixing New Physics in Other Precision Meas.s Z’ Oblique Sterile NuTeV Corrections Mixing Anomaly?

  19. Precision Meas.s: Energy – Intensity Connection ~ c E Energy Frontier Facility Intensity Frontier Facility The Flavor Sector Mixings, Masses, CPV, FCNC, LFV, … The Gauge Sector Higgs EWSB EWSB – Flavor Intimate Relationship: No EWSB  fermions degenerate  no visible flavor effect Intensity Frontier can probe new physics at a scale >> TeV scale.
