  1. W. G. SCOTT RAL PHYS. ANAL. MEET. 13 JUNE 2006 . (NB. BELLE HAS 92K Bs-Bs EVENTS FROM Y(5s) !!)

  2. CABIBBO FAVOURED B-DECAYS (VIA TREE DIAGRAMS) B’s DECAY TO D’s (ALMOST ALWAYS) . eg.

  3. . THE ABOVE ARE RARE B-DECAYS (FCNC) ONLY VIA LOOP DIAGRAMS, eg. PENGUINS:

  4. MEASURES Vts: (Vtb ~ 1) .

  5. .

  6. .

  7. “b <-> s” UNITARITY TRIANGLE A long & thin triangle – not “the” unitarity triangle:

  8. MEASURES Vts: (Vtb ~ 1)

  9. WHAT IS ACTUALLY HAPPENING??!! 1) GENERATED PT=5 GeV PHOTONS 5000 events/photons in 10 files (500 events per file) /castor/cern.ch/user/s/scottw/ dig1104/Phot_Pt_5_000(01-10).dig.pool.root 2) RAN PYTHIA-B AT CERN (help from: J. Catmore) Interactively with and without transformation files. Wrong channel: Bs -> J/Psi phi (but related). Wromg Computer: Move to CSF at RAL. Need to import S. Virets code into PYTHIA-B. Summer student G. Brown arrives 22 June.
