(16.9 ±3.5 ) % S=1.1 [a]ThisisaweightedaverageofD ± (44%) and D0 (56%) branching fractions. See “D + andD 0 → (η anything) / (total D + and D0 )” under “D + Branching Ratios” in these Particle Listings. [b] This value averages the e + and µ + branching fractions, after making a small phase-space adjustment to the µ + fraction to be able to use it as an e + fraction; hence our ℓ + here is really an e + . [c] 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. [d] The two experiments measuring this fraction are in serious disagreement. See the Particle Listings. [e] 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. [f ] However, these upper limits are in serious disagreement with values obtained in another experiment. [g] This mode is not a useful test for a ∆C=1 weak neutral current because both quarks must change flavor in this decay. [h] The value is for the sum of the charge states of particle/antiparticle states indicated. HTTP://PDG.LBL.GOV Page 9 Created: 6/29/1998 12:22
