متن کاملBeauty Semileptonic Branching Ratios
Recent measurements of inclusive and exclusive semileptonic b branching ratios are reviewed. Model-independent analyses from ARGUS and CLEO connrm the value B(b ! ``X) = 10:4%, while new analyses from ALEPH obtain higher values above 11%. The diierence is not consistent with measured values of b hadron lifetime. New measurements of B(B ! D ? ``) from CLEO and ALEPH are in good agreement. First ...
متن کاملMeasurement 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 کاملPrecise measurements of the leptonic branching ratios of the tau lepton.
Precise measurements are reported for the leptonic branching ratios of the T lepton from the reaction e+e+ T+Tobserved with the MAC detector operating at PEP. Results from samples in which one T decays into three charged particles and the other to e or /,L are B, = 0.180 f 0.009 f 0.006 and B, = 0.183f0.009f0.005. A sample of ep events gives Be-B, = 0.0288f0.0017f0.0019. With the assumption of ...
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 +...
