  1. B Physics and the High Energy Frontier — (Super) B Factory/Tevatron (LHC)

  2. Strategy / Disclaimer • Phenomena Pertinent to BSM • Physics (vs Expt’l detail — not always most up-to-date) • [No “B Chemistry” (goto CKM meeting (Tim Gershon), if desired) • Short-term impact  This Decade 2010−2019 and not too tricky ... vs 2000−2009 • “Traditional” on BSM topics • Cannot cite all TH work, • but unabashedly promote own pheno work

  3. New Physics Hints in B Decays and Collider Outlook January 7, 2006, WHEPP9 @ Bhubaneswar 1

  4. Search for TeV Scale Physics in Heavy Flavour Decays July 28, SUSY2007 @ Karlsruhe 1

  5. Thanks for WHEPP IX initiation! Makes me look forward to 2014 …

  6. Will skip Bottomonium, D, K, t, m

  8. 0. “Forward to the Past” as Intro Search for Future Influence from L.H.C Authors:Holger B. Nielsen, Masao Ninomiya (Submitted on 13 Jul 2007) SuperPowered Theorists ? or Wormhole to the Future? Wormhole from/to the Future? 6

  9. Beware the Nielsen-Ninomiya Effect !

  10. What If ? sin2b history (1999-2005) b/f1=-argVtd Discovery claimed R. Cahn -- SSI-2006 7

  11. b  d transitions consistent with SM Our Main Theme What about b  s transitions ? 10

  12. The Nobel Prize in Physics 2008 "for the discovery of the origin of the broken symmetry which predicts the existence of at least three families of quarks in nature" "for the discovery of the mechanism of spontaneous broken symmetry in subatomic physics" CPViolation in SM 7 October 2008 B Factory

  14. I. Introduction to CP Violation

  15. CPV i i QM CP Asymmetry needs both CP Conserv/Violating Phase CP Violation Primer AntiParticle Process Particle Process

  16. i in Dynamics: CPV & BAU Baryon Asymmetry of Universe (everyone can feel ElectroMagnetism: Charge e is Real. “We” Understand: Gauge Charge is Real. Imagine a Complex Coupling : True, or, Possible, for Yukawa (湯川) Coupling of quarks/leptons to Higgs boson(s)... Quantum InterferenceinAmplitudeMore Interesting How CP Violation Appears

  17. (1966) CPV & BAU (& U): The Sakharov View • Baryon Number V iolation • CP Violation(“Direction”) • Nonequilibrium (“Direction”) 10-9 Matter left! Bang Us Pair Annihilation (  Cosmic Microwave Background ) Equal Matter -Antimatter

  18. Complex Dynamics VCKM 3x3 “Rotation” Unitary Need presence of all 3 generations to exhibit CPV in Standard Model

  19. Wolfenstein Parametrization to O(5) Unique CPV Phase: Common Area of Triangle N.B. geometric picture

  20. CPV Phase Most Intuitive: “Direct” CPVin B → Kp DCPV Interference Penguin Tree N.B. Would need also CP Conserving Phase Differenced

  21. CP Violation History Mixing(-dep.) Direct K: 1964 1999 0.0004% 0.2% B: 2001 2004 70% 10%

  22. Kobayashi’s Nobel slides 51

  23. Jarlskog’s Invariant for CPV CPVso far only observed in KM ... • Nontrivial CPV Phase • Nontrivial • All like-charge quark pairs nondegenerate, • Otherwise  Back to 2-gen. and CPV vanish. 52

  24. Kobayashi’s Nobel slides Jseems short of the Universe by at least 10-10 53

  25. CPV & BAU definitely a H.E. Frontier

  26. II. CPV in b  sw/ Boxes and Penguins The Current Frontier tm Echoes DS; DAKp;sin2FBs; [ACP(B+  J/yK+)]

Hadronic effect or new physics?  A(K0p0) = -0.12±0.11; S(K0p0) = +0.33±0.21  Super B factory! P. Chang 6
