Workshop

A workshop on semileptonic and
radiative rare B decays


Questions for session 4 link to papers
  1. Is there any reason why the measured |Vcb| from exclusive decays could be different from the inclusive measurements?
  2. OPE convergence:
    • What is the uncertainty associated with neglecting higher order or other terms in the expansion?
    • Is there a particular observable which strongly tests OPE convergence (i.e., which observables are most sensitive to higher order terms)?
  3. OPE mass schemes:
    • What are the advantages/disadvantages of the various schemes?
    • Are the parameters in different schemes simply related to one another?
  4. Quark-hadron duality:
    • To what extent do we expect it to be violated?
    • How inclusive must our observables be in order to expect it to be obeyed?
  5. What other observables constrain OPE parameters?
    • Higher order moments?
    • b to s gamma photon energy moments?
    • lepton-neutrino Q^2?
  6. OPE fits to semileptonic moments:
    • How do we treat m_c?
    • How many parameters are free in the fit?
    • What are the uncertainties of those that are fixed in the fit?
  7. Are the parameters extracted from b to clnu (especially mb) applicable to b to s gamma, b to s ll, or b to ulnu?
