Measurement of the $Ω_{c}^{0}$ Lifetime

FOCUS collaboration, J. M. Link

The FOCUS experiment(FNAL-E831) has used two channels, $Ω^{-} π^{+}$ and $Ξ^{-} K^{-} π^{+} π^{+}$ ,to measure the lifetime of the $Ω_{c}^{0}$ charmed baryon. From a sample of $64 \pm 14$ signal eve…

Measurement of the D+ and Ds+ decays into K+K-K+

The FOCUS Collaboration

We present the first clear observation of the doubly Cabibbo suppressed decay D+ --> K-K+K+ and the first observation of the singly Cabibbo suppressed decay Ds+ --> K-K+K+. These s…

The Target Silicon Detector for the FOCUS Spectrometer

The FOCUS Collaboration

We describe a silicon microstrip detector interleaved with segments of a beryllium oxide target which was used in the FOCUS photoproduction experiment at Fermilab. The detector was…

Measurement of Natural Widths of Sigma-c-0 and Sigma-c-++ Baryons

FOCUS Collaboration

In this paper we present a measurement of the natural widths of $Σ_{c}^{0}$ and $Σ_{c}^{++}$ . Using data from the FOCUS experiment, we find $Γ (Σ_{c}^{0}) = 1.55 + 0.41/ - 0.37 \pm 0.38$ MeV/c^2…

Study of the P-wave charmonium state χ_{cJ} in ψ(2S) decays

J. Z. Bai

The processes $ψ (2 S) \to γ π^{+} π^{-}$ , $γ K^{+} K^{-}$ and $γ p p ˉ$ have been studied using a sample of $3.7 \times 1 0^{6}$ produced $ψ (2 S)$ decays. We determine the total width of the $χ…
