Provide latest results and averages of branching
fractions, Direct CP asymmetry (ACP), polarization fractions and other ovservables in b-hadron decays to final states that do not contain charm hadrons or charmonia mesons.
Organisation of the tables
Tables are available for:
Branching fractions of charmless mesonic B0 and B± meson decays
Branching fractions and other observables of radiative and leptonic B0 and B± meson decays, including LFV and LNV modes
Branching fractions of charmless baryonic B0 and B± meson decays
Direct ACP in b-hadron decays
Polarization measurements in b-hadron decays
Branching fractions of charmless mesonic B0s meson decays
Branching fractions of charmless decays of b-baryons
Branching fractions of charmless mesonic Bc meson decays
At the end of some of these sections we give a list of results that were not included in the tables.
are the measurements of distributions, such as differential branching fractions or longitudinal
polarizations, which are measured in different binning schemes by the different collaborations,
and thus cannot be directly used to obtain averages.
1. Preliminary conference results for which there is written documentation are included.
2. Average is performed using the
PDG method (see Sec. 10).
In cases where χ2/dof > 1, we do not usually scale the resulting uncertainty.
3. For branching fractions, we provide either averages or the most stringent upper limits.
If one or more experiments have measurements with >4σ for a decay channel, all available
central values for that channel are used in the averaging. We also give central values and
errors for cases where the significance of the average value is at least 3σ, even if no single
measurement is above 4σ. The most stringent limit will be used for branching fractions that
do not satisfy this criterion.
4. For ACP we provide averages in all cases.
Old results have been removed, but can be obtained upon request.
