Measurement of the absolute branching fraction of Ds+→τ+ντ decay
Physical Review Letters 100:16 (2008)
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.Higgs boson searches in CP-conserving and CP-violating MSSM scenarios with the DELPHI detector (The European Physical Journal C (2008) 56 (1-16) DOI:10.1140/epjc/s10052-007-0506-1)

Measurement of the mass and width of the W boson in e+e - collisions at √s = 161-209 GeV
European Physical Journal C 55:1 (2008) 1-38
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 -→ℓν̄Absolute branching fractions of Cabibbo-suppressed D → K(K)over-bar decays
