Workshop

A workshop on semileptonic and
radiative rare B decays


Questions for session 3 link to papers
  1. Different kinetic variables: q^2, hadron mass M_had, lepton energy E_l or combinations? Which region is easiest for theoretical interpretations?
  2. What is the impact of hadronization on measurement?
  3. Which is the best way to build the b->ulnu model?
    • How to combine the exclusive vs noresonant components?
    • s-sbar popping estimate?
  4. What if anything can we learn from endpoint measurements?:
    • What do we know about the 1/mb terms?
  5. What is the impact of shape functions and non-perturbative parameters?
  6. OPE for b -> u l nu / b -> s gamma:
    • Which variables/moments are best suited?
    • Would the non-perturbative parameters from b -> u l nu be better for the determination of |Vub|?
    • Comparison of b -> u and b -> s gamma?
  7. What are the difference between B+ and B0 decays? What can we learn?
