Measurement of tau branching ratios.
Using the data accumulated at LEP in 1989 and 1990 with the A L E P H detector, the inclusive and exclusive branching ratios o f the r lepton have been measured assuming lepton universality in Z ~ decays. The inclusive branching fractions for the r decay into one, three, and five charged particles have been determined to be (85.45 _+ 0.97)%, (14.35 _+ 0.48)%, and (0.10 _+ 0.05)%, respectively, ...
متن کاملMeasurement of the Ratios of Branching Fractions
We present the measurement of the ratios of branching fractions B(B ° -+ D-r + ) to B(Bo -+ D--+), and B(B2 -+ OD-rr+rr ) to B(Bo -D-urx+r+-r-). We analyze data taken with the CDF II detector that corresponds to an integrated luminosity of 355 pb 1 in pp collisions at V = 1.96 TeV at the Fermilab Tevatron. Using a novel displaced track trigger we reconstruct 494 ± 28 B ° -+ D;-r+ decays, 8098 +...
متن کاملMeasurement of tau lifetime and branching ratios.
Precise results are reported for the T lepton lifetime and several I branching ratios obtained with the MAC detector operating at PEP at JS = 29 GeV. We find T ~=(3.15?0.36?0.41~10-~~ sec. Results for the topological branching ratios Bl, Bs, 8s (7 decaying into 1, 3, 5 charged particles) are B+l-8~=0.133~0.003~0.006 and B5<0.0017 at the 95% confidence level. The fraction of all 3-prong decays u...
متن کاملMeasurement of the branching ratios of the decays
From 56 days of data taking in 2002, the NA48/1 experiment observed 6316 Ξ0 → Σeνe candidates (with the subsequent Σ + → pπ0 decay) and 555 Ξ0 → Σ+eνe candidates with background contamination of 215 ± 44 and 136 ± 8 events, respectively. From these samples, the branching ratios BR(Ξ0 → Σeνe) = (2.51 ± 0.03stat±0.09syst)×10 and BR(Ξ0 → Σeνe) = (2.55±0.14stat±0.10syst)×10 were measured allowing t...
متن کاملMeasurement of Branching Ratios and CP Asymmetries in B − →
We present preliminary results of the analysis of B → Dh decays, with h = π,K and the D reconstructed in the channelsKπ, Kπππ, Kππ and in the CP eigenstate KK, using data collected by the BABAR detector during the years 2000-2002 at the PEP-II asymmetric-energy B Factory at SLAC. We have measured the ratio of the branching fractions R ≡ B(B − → DK) B(B− → Dπ) = (8.31 ± 0.35 ± 0.20)% and the dir...
