A workshop on semileptonic and
radiative rare B decays

Questions for session 5 
link to papers 

 Form Factors, pseudoscalar 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?
 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?
 How firm are the isospin relations, relating B0 to B+ decays?
 Higher mass states and nonresonant in charmless semileptonic decays:
 What is known about higher mass states?
 What is known about nonresonant contribution at higher
masses and below 1.5 GeV?
 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?
