Ratios of bottom meson branching fractions involving J/ psi mesons and determination of b quark fragmentation fractions.
We report a measurement of the ratios of the decay rates of the B, B and B s mesons into exclusive final states containing a J/ψ meson. The final states were selected from 19.6 pb of pp̄ collisions recorded by the Collider Detector at Fermilab. These data are interpreted to determine the b quark fragmentation fractions fu, fd and fs. We also determine the branching fractions for the decay modes ...
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 کاملAbsolute measurement of hadronic branching fractions of the Ds+ meson.
The branching fractions of D(s)(+/-) meson decays serve to normalize many measurements of processes involving charm quarks. Using 298 pb(-1) of e(+)e(-) collisions recorded at a center of mass energy of 4.17 GeV, we determine absolute branching fractions for eight D(s)(+/-) decays with a double tag technique. In particular we determine the branching fraction B(D(s)(+)-->K(-)K(+}pi(+))=(5.50+/-0...
متن کاملBranching Fractions
From an analysis of the current world averages of the K→ ν̄l l (γ) and τ→ντ K − branching fractions, we derive, within the framework of type II Higgs doublets models such as the Minimal Supersymmetric Extension of the Standard Model, tanβ/mH < 0.21 GeV at a 90% confidence limit.

متن کاملDirect measurements of charmed-D-meson hadronic branching fractions.
A new technique is applied to data collected at the +(3770) resonance to derive charmed D meson branching fractions without relying on the measurement of D production cross sections. Measurements are presented for three decay modes of the Do (K-n+, K-?r-w+r+ and K-7r+r ") and four decay modes of the D+ (K-7r+rr+, K-x+r+~~, Kt?r+ and Kfr+7r "). The resulting branching fractions are significantly...
