B-particle organization

Many measurements of B decays involve admixtures of B hadrons. Previously we arbitrarily included such admixtures in the B± section, but because of their importance we have 0 created two new sections: “B±/B Admixture” for Υ(4S) 0 0 results and “B±/B /Bs /b-baryon Admixture” for results at higher energies. Most inclusive decay branching fractions and χb at high energy are found in the Admixture sections. 0 0 0 0 B -B mixing data are found in the B section, while Bs - 0 0 0 Bs mixing data and B-B mixing data for a B /Bs admixture 0 are found in the Bs section. CP-violation data are found in 0 0 the B±, B , and B± B Admixture sections. b-baryons are found near the end of the Baryon section. The organization of the B sections is now as follows, where bullets indicate particle sections and brackets indicate reviews. B • ± mass, mean life, CP violation, branching fractions B0 • mass, mean life, B0-B0 mixing, CP violation, branching fractions B /B0 Admixtures • ± CP violation, branching fractions B /B0/B0/b-baryon Admixtures • ± s mean life, production fractions, branching fractions

B− modes are charge conjugates of the modes below. Modes which do not 0 identify the charge state of the B are listed in the B±/B ADMIXTURE section.

0 0 + The branching fractions listed below assume 50% B B and 50% B B− production at the Υ(4S). We have attempted to bring older measurements up to date by rescaling their assumed Υ(4S) production ratio to 50:50 and their assumed D, Ds , D∗, and ψ branching ratios to current values whenever this would aﬀect our averages and best limits signiﬁcantly.

Indentation is used to indicate a subchannel of a previous reaction. All resonant subchannels have been corrected for resonance branching fractions to the ﬁnal state so the sum of the subchannel branching fractions can exceed that of the ﬁnal state.

For inclusive branching fractions, e.g., B D X , the values usually are → ± multiplicities, not branching fractions. They can be greater than one.

We have attempted to bring older measurements up to date by rescaling their assumed Υ(4S) production ratio to 50:50 and their assumed D, Ds , D∗, and ψ branching ratios to current values whenever this would aﬀect our averages and best limits signiﬁcantly.

For inclusive branching fractions, e.g., B D X , the values usually are → ± multiplicities, not branching fractions. They can be greater than one.

The branching fraction measurements are for an admixture of B mesons at the Υ(4S). The values quoted assume that B(Υ(4S) B B) = 100%. → For inclusive branching fractions, e.g., B D anything, the treatment → ± of multiple D’s in the final state must be defined. One possibility would be to count the number of events with one-or-more D’s and divide by the total number of B’s. Another possibility would be to count the total number of D’s and divide by the total number of B’s, which is the definition of average multiplicity. The two definitions are identical if only one D is allowed in the final state. Even though the “one-or-more” definition seems sensible, for practical reasons inclusive branching fractions are almost always measured using the multiplicity definition. For heavy final state particles, authors call their results inclusive branching fractions while for light particles some authors call their results multiplicities. In the B sections, we list all results as inclusive branching fractions, adopting a multiplicity definition. This means that inclusive branching fractions can exceed 100% and that inclusive partial widths can exceed total widths, just as inclusive cross sections can exceed total cross section.

Only the highest energy results (LHC, LEP, Tevatron, Sp pS) are used in the branching fraction averages. In the following, we assume that the production fractions are the same at the LHC, LEP, and at the Tevatron.

For inclusive branching fractions, e.g., B D anything, the values → ± usually are multiplicities, not branching fractions. They can be greater than one.

PRODUCTION FRACTIONS

The production fractions for weakly decaying b-hadrons at high energy have been calculated from the best values of mean lives, mixing parameters, and branching fractions in this edition by the Heavy Flavor Averaging Group (HFLAV) as described in the note “B0-B0 Mixing” in the B0 Particle Listings. We no longer provide world averages of the b-hadron production fractions, where results from LEP, Tevatron and LHC are averaged together; indeed the available data (from CDF and LHCb) shows that the fractions depend on the kinematics (in particular the pT ) of the

produced b hadron. Hence we would like to list the fractions in Z decays instead, which are well-deﬁned physics observables. The production fractions in p p collisions at the Tevatron are also listed at the end of the section. Values assume

NOTES

[a] See the review on “Form Factors for Radiative Pion and Kaon Decays” for deﬁnitions and details. + + [b] Measurements of Γ(e νe )/Γ(µ νµ) always include decays with γ’s, + + and measurements of Γ(e νe γ) and Γ(µ νµ γ) never include low- energy γ’s. Therefore, since no clean separation is possible, we consider the modes with γ’s to be subreactions of the modes without them, and + + let [Γ(e νe ) + Γ(µ νµ)]/Γtotal = 100%.

[c] See the π± Particle Listings for the energy limits used in this measurement; low-energy γ’s are not included. [d] Derived from an analysis of neutrino-oscillation experiments. 13 [e] Astrophysical and cosmological arguments give limits of order 10− . [f ] Forbidden by angular momentum conservation. [g] C parity forbids this to occur as a single-photon process. [h] The ωρ interference is then due to ωρ mixing only, and is expected to 0 + 0 + be small. If e µ universality holds, Γ(ρ µ µ−)=Γ(ρ e e−) 0.99785. → → × [i]See the “Note on a1(1260)” in the a1(1260) Particle Listings in PDG 06, Journal of PhysicsG33 1 (2006). [j] Our estimate.

[rr] This is not a test for the ∆C=1 weak neutral current, but leads to the + + π ℓ ℓ− final state. [ss] This mode is not a useful test for a ∆C=1 weak neutral current because both quarks must change flavor in this decay.
