B-particle organization I 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 created two new sections: " B • 0 Admixture" for 7"(45) results and "B+/B~176 A d m i x t u r e " for results at higher energies. Most inclusive decay branching fractions are found in the Admixture sections. B ~ ~ mixing data are found in the B ~ section, while Bs-B s ~--o mixing data and BB mixing data for a B~ ~ admixture are found in the Bs0 section. CP-violation data are found in the B ~ section, bbaryons 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. 9 B+ mass, mean life branching fractions 9 B0 mass, mean life branching fractions polarization in B ~ decay

ADMIXTURE I The branching fraction measurementsare for an admixture of B mesonsat the T(45). The values quoted assume that B(T(4S) -~ BB) = 100%.
thing B -~ ~b(2S)anything
For inclusive branching fractions, e.g.. B ~ D4- anything, the treatment of multiple D's in the final state must be defined. One possiblity would be to count the number of events with one-oPmore 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 when only one of the specified particles is allowed in the final state. Even though the "one-or-more" definition seemssensible, for p~actical 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 sections.

The branching fraction measurements are for an admixture of B mesons and baryons at energies above the T(4S). Only the highest energy results (LEP, Tevatron, SpaS) are used in the branching fraction averages. In the following, we assume that the production fractions are the same at the LEP and at the Tevatron.

For inclusive branching fractions, e.g., B ~ D • anything, the treatment of multiple D's in the final state must be defined. One possiblity 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 when only one of the specified particles 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 sections.

When a quantity has "(S . . . . )" to its right, the error on the quantity has been enlarged by the "scale factor" S, defined as S = ~ 1), where N is the number of measurements used in calculating the quantity. We do this when S > i, which often indicates that the measurements are inconsistent. When S > 1.25, we also show in the Particle Listings an ideogram of the measurements. For more about S, see the Introduction.

Meson Summary Table [d] Derived from an analysis of neutrino-oscillation experiments. [e] Astrophysical and cosmological arguments give limits of order 10-13; see the ~r~ Particle Listings. [f] See the "Note on the Decay Width F(T/ -~ "f~')" in our 1994 edition, Phys. Rev. DS0, 1 August 1994, Part I, p. 1451. [E] C parity forbids this to occur as a single-photon process. [h] See the "Note on scalar mesons" in the fo(1370) Particle Listings. The interpretation of this entry as a particle is controversial. [f] See the "Note on p(770)" in the p(770) Particle Listings. [./] The e+ e- branching fraction is from e+ e - --~ ~r+ 7r- experiments only. The ~ p interference is then due to ~ p mixing only, and is expected to be small. If e# universality holds, r(p 0 --, /~+#-) = F(p0 --~ e+e - ) • 0.99785. [k] See the "Note on scalar mesons" in the f0(1370) Particle Listings. [f] See the "Note on a1(1260)" in the a1(1260 ) Particle Listings. [m] This is only an educated guess; the error given is larger than the error on the average of the published values.

[v] The definition of the slope parameter Eof the K --* 3~r Dalitz plot is as follows (see also "Note on Dalitz Plot Parameters for K --* 3~r Decays" in the K - Particle Listings):
IMI =

[w] For more details and definitions of parameters see the Particle Listings. [x] Most of this radiative mode, the low-momentum 3' part, is also included in the parent mode listed without 3"s.

Test of direct CP violation since the indirect CP-violating and CP-conserving contributions are expected to be suppressed. ~ ] See the "Note on fo(1370)" in the f0(1370) Particle Listings and in the 1994 edition. [kk] See the note in the L(1770) Particle Listings in Reviews of Modern Physics 56 No. 2 Pt. I1 (1984), p. $200. See also the "Note on K2(1770 ) and the/(2(1820)" in the K2(1770 ) Particle Listings. [If] See the "Note on K2(1770 ) and the K2(1820)" in the K2(1770 ) Particle Listings. This result applies to Z ~ ---* cs decays only. Here t + is an average (not [ram] a sum) of e+ and #+ decays. [nn] This is a weighted average of D :1: (44%) and D O (56%) branching fractions. See "D+andD ~ -~ (7/anything) / (total D + and DO) '' under "D + Branching Ratios" in the Particle Listings. [oo] This value averages the e+ and #+ branching fractions, after making a small phase-space adjustment to the/~+ fraction to be able to use it as an e+ fraction; hence our t + here is really an e+, [pp] An t indicates an e or a/~ mode, not a sum over these modes. [qq] The branching fraction for this mode may differ from the sum of the submodes that contribute to it, due to interference effects. See the relevant papers in the Particle Listings. [rr] The two experiments measuring this fraction are in serious disagreement. See the Particle Listings. [ss] This mode is not a useful test for a A C = I weak neutral current because both quarks must change flavor in this decay. [tt] This D~ O limit is inferred from the D~ ~ mixing ratio F(K+Tr - (via D~ / F(K-7r +) near the end of the D o Listings. [uu] The experiments on the division of this charge mode amongst its submodes disagree, and the submode branching fractions here add up to considerably more than the charged-mode fraction. [vv] However, these upper limits are in serious disagreement with values obtained in another experiment. [ww] For now, we average together measurements of the X e+ r,e and X/~+ vp branching fractions. This is the average, not the sum. [xx] This branching fraction includes all the decay modes of the final-state resonance. Lvy] This value includes only K + K - decays of the f0(1710), because branching fractions of this resonance are not known. [zz] This value includes only 7r+ 7r- decays of the fo(]500), because branching fractions of this resonance are not known. [aaa] B ~ and B ~ contributions not separated. Limit is on weighted average of the two decay rates.
[bbb] These values are model dependent. See 'Note on Sernileptonic Decays' -
