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 re- views.

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 frac- tions 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.

Reactions indicate the weak decay vertex and do not include mixing. 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 frac- tions 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.

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 to- tal 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” def- inition 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.

B modes are charge conjugates of the modes below. Reactions indicate the weak decay vertex and do not include mixing.

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.

The modes below are listed for a b initial state. b modes are their charge conjugates. Reactions indicate the weak decay vertex and do not include mixing. Scale factor/ p b DECAY MODES Fraction (Γi /Γ) Confidence level (MeV/c)

PRODUCTION FRACTIONS

The production fractions for weakly decaying b-hadrons at high energy have been calculated from the best values of mean lives, mixing parame- ters, 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. The production fractions in b-hadronic Z decay or p p collisions at the Tevatron are also listed at the end of the section. Values assume

f d The notation for production fractions varies in the literature ( d , B0 , f (b B0), Br(b B0)). We use our own branching fraction notation → → here, B(b B0). → Note these production fractions are b-hadronization fractions, not the con- ventional branching fractions of b-quark to a B-hadron, which may have considerable dependence on the initial and final state kinematic and pro- duction environment.

NOTES

[a] See the “Note on π ℓ ν γ and K ℓ ν γ Form Factors” in ± → ± ± → ± the π± Particle Listings 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 measure- ment; 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− ; see the π0 Particle Listings. [f ] C parity forbids this to occur as a single-photon process.

[g] See the “Note on scalar mesons” in the f0(500) Particle Listings . The interpretation of this entry as a particle is controversial. [h] See the “Note on ρ(770)” in the ρ(770) Particle Listings . [i] The ω ρ interference is then due to ω ρ 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. → → × [j] See the “Note on scalar mesons” in the f0(500) Particle Listings . [k]See the “Note on a1(1260)” in the a1(1260) Particle Listings in PDG 06, Journal of PhysicsG33 1 (2006).

See the relevant papers in the Particle Listings. + [uu] These subfractions of the K − 2π mode are uncertain: see the Particle Listings. + + 0 0 + [vv] Submodes of the D K − 2π π and K S 2π π− modes were studied by ANJOS 92C→and COFFMAN 92B, but with at most 142 events for the first mode and 229 for the second – not enough for precise results. With nothing new for 18 years, we refer to our 2008 edition, Physics Letters B667 1 (2008), for those results. [xx] The unseen decay modes of the resonances are included. [yy] This is not a test for the ∆C=1 weak neutral current, but leads to the + + π ℓ ℓ− final state. [zz] This mode is not a useful test for a ∆C=1 weak neutral current because both quarks must change flavor in this decay. [aaa] In the 2010 Review, the values for these quantities were given using a measure of the asymmetry that was inconsistent with the usual defini- tion.
