Workshop

A workshop on semileptonic and
radiative rare B decays


Questions for session 5 link to papers
  1. Form Factors, pseudo-scalar decays:
    • pi l nu is simplest, both experimentally and theoretically! What is the best ansatz for a q^2 dependence of the form factor for the whole q^2 range?
    • What are the uncertainties for predictions for q^2 dependence of the form factor?
    • What are the prospects for better predictions? Lattice? LCSR?
    • What can we learn from eta l nu?
    • What else can we learn from form factors?
  2. Form Factors, vector decays (rho,omega) l nu:
    • What can we learn from the vector form factor measurements?
    • What can we learn from omega l nu, as compared to rho l nu?
  3. How firm are the isospin relations, relating B0 to B+ decays?
  4. Higher mass states and non-resonant in charmless semileptonic decays:
    • What is known about higher mass states?
    • What is known about non-resonant contribution at higher masses and below 1.5 GeV?
  5. FF from pi(rho)l nu to K(K*) gamma:
    • Can we relate FF for exclusive u l nu and s gamma (pi(rho)l nu - K(K*) gamma)?
    • What can we learn from high statistics measurements on K* gamma and k gamma?
