Provide latest results and averages of branching fractions, direct CP asymmetry (ACP), polarization fractions and other observables 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.
Typical cases 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.
Preliminary conference results for which there is written documentation are included.
Average is performed using the PDG method (see Sec. 10)
- In cases where χ2/dof > 1, we do not usually scale the resulting uncertainty.
For branching fractions, we provide either averages or the most stringent upper limits.
- If one or more experiments have measurements with a significance > 3σ for a decay channel, all available central values for that channel are used in the averaging. The most stringent limit will be used for branching fractions that do not satisfy this criterion.
For ACP we provide averages in all cases.
April 2019 (latest)
The April 2019 pages contain tables and plots that include results put on the arXiv until the end of the April 2019. They cover results presented in the winter conferences of 2019. The PDG results have been updated to those of PDG live (end of 2017), as from the December 2017 pages.
Older results have been removed, but can be obtained upon request.
