Abstract:

The branching fractions of Ds± meson decays serve to normalize many measurements of processes involving charm quarks. Using 298pb-1 of e+e- collisions recorded at a center of mass energy of 4.17 GeV, we determine absolute branching fractions for eight Ds± decays with a double tag technique. In particular we determine the branching fraction B(Ds+→K-K+π+)=(5.50±0.23±0.16)%, where the uncertainties are statistical and systematic, respectively. We also provide partial branching fractions for kinematic subsets of the K-K+π+ decay mode. © 2008 The American Physical Society.

Abstract:

Using a sample of tagged Ds+ decays collected near the Ds*±Ds peak production energy in e+e- collisions with the CLEO-c detector, we study the leptonic decay Ds+→τ+ντ via the decay channel τ+→e+νeν̄τ. We measure B(Ds+→τ+ντ)=(6. 17±0.71±0.34)%, where the first error is statistical and the second systematic. Combining this result with our measurements of Ds+→μ+νμ and Ds+→τ+ντ (via τ+→π+ν ̄τ), we determine fDs=(274±10±5)MeV. © 2008 The American Physical Society.

Abstract:

A measurement of the W boson mass and width has been performed by the DELPHI collaboration using the data collected during the full LEP2 programme (1996-2000). The data sample has an integrated luminosity of 660 pb-1 and was collected over a range of centre-of-mass energies from 161 to 209 GeV. Results are obtained by applying the method of direct reconstruction of the mass of the W from its decay products in both the W+W -→ℓν̄ℓqq̄′ and W +W-→qq̄′ q̄q′ channels. The W mass result for the combined data set is MW = 80.336 ± 0.055 (Stat.) ± 0.028 (Syst.) ± 0.025 (FSI) ± 0.009 (LEP) GeV}/c2, where FSI represents the uncertainty due to final state interaction effects in the qq̄′ q̄q′ channel, and LEP represents that arising from the knowledge of the collision energy of the accelerator. The combined value for the W width is ΓW = 2.404 ± 0.140 (Stat.) ± 0.077 (Syst.) ± 0.065 (FSI) GeV/c 2. These results supersede all values previously published by the DELPHI collaboration. © 2008 Springer-Verlag / Società Italiana di Fisica.
