Presentation Transcript

  1. Vub exclusive (CKM workshop) • Many new measurements, • agreement in general • CLEO performed new • analysis in bins of q2 • reducing FF dependence • Mean of exclusive analyses • starts to be systematically • below the inclusive one • Mentioned the recoil of fully • B tags to minimize the • systematic unc. • Problems in averaging: how • can we quote and weight FF • dependence? Daniele del Re

  2. Vub exclusive (CKM workshop) We can reject theoretical models using the q2 distribution Daniele del Re

  3. Vub inclusive (CKM workshop) • 4 new measurements based • on Mx from B factories • discussion about performing • averages • established common strategy • between BaBar and Belle • (both for experimental and • theoretical uncertainties) • not much time for discussion • with theorists (close to zero • actually) Daniele del Re

  4. Vub inclusive (CKM workshop) Recoil of B D* l n in Belle Daniele del Re

  5. Vub inclusive (CKM workshop) • Annealing method in Belle: • divide the event in two Bs, many combinations • take the one with the highest prob. to be signal (using a PDF made by a combination of discriminating variables) q2> 7 GeV2 MX < 1.5 GeV q2[GeV2] MX [GeV] Daniele del Re
