A workshop on semileptonic and
radiative rare B decays
 |
| Questions for session 2 |
link to papers |
|
- What are shape functions?:
- Are they truly properties of the B meson, and thus do not depend
on the decay mode?
- What is the appropriate parameterization of the shape function?:
- What additional informations do we have on the shape function (positivity,
behavior of the tails,...)?
- Can we avoid the long tails?
- How does the parameterization relate to the parameters Lambda_bar and L_1?
- How do we parametrize the errors from 1/m_b effects (subleading shape functions)?
- How do we measure the shape functions?
- How do we relate Lambda_bar and L_1 determined from b-> c
to b -> u and b -> s gamma?:
- What is the impact of energy cuts on leptons or photons?
- Are there ways to measure |Vub| without the use of shape
functions?
