  Purpose

    Provide latest results and averages of branching fractions and Acp

  Scope
   
        Charmless Mesonic B Decays
       
  Radiative B Decays
     
  Leptonic B Decays
        Baryonic B Decays
            Mesonic B Decays with Charm are not included

  Method

    1. Preliminary conference results for which there is written documentation are included.
    2. Average is performed using the PDG method (see Sec. 10).
    3. The most stringent limit will be used for modes without observations.
    4. All central values, if available, are averaged for channels that are observed (4 sigma)
           by at least one experiment OR if the average is minimally significant (3 sigma).

  Results

    In addition to the measurements posted below, new tables and plots are available around March 1 (prior to the winter conferences) and just before the summer conference. Contact the HFAG rare members listed below for information on how to obtain the latest results which may not yet be posted officially.
