A workshop on semileptonic and
radiative rare B decays

Questions for session 3 
link to papers 

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