Study of Hadronic Five-Body Decays of Charmed Mesons
M. Wahl
We study the decay of D+ and Ds+ mesons into charged five body final states, and report the discovery of the decay mode D+ -> K+K-Pi+Pi+Pi-, as well as measurements of the decay mo…
Observation of a 1750 MeV/c^2 Enhancement in the Diffractive Photoproduction of K^+K^-
FOCUS Collaboration
Using the FOCUS spectrometer with photon beam energies between 20 and 160 \gev, we confirm the existence of a diffractively photoproduced enhancement in at 1750 \mevcc wit…
A new measurement of the lifetime
J. M. Link
Using data collected by the Fermilab experiment FOCUS, we measure the lifetime of the charmed baryon (Ξ_{c}^{o}) using the decay channels (Ξ_{c}^{o}\to Ξ^{-}π^{+}) and (Ξ_{c}^{o}\t…
Measurements of Relative Branching Ratios of Decays into States Containing
J. M. Link
We have studied the Cabibbo suppressed decay (Λ_{c}^{+}\to Σ^{+}K^{*0}(892)) and the Cabibbo favored decays (Λ_{c}^{+}\to Σ^{+}K^{+}K^{-}), (Λ_{c}^{+}\to Σ^{+}ϕ) and (Λ_{c}^{+}\to…
Evidence for new interference phenomena in the decay D+ to K- pi+ mu+ nu
The FOCUS Collaboration
Using a large sample of charm semileptonic decays collected by the FOCUS photoproduction experiment at Fermilab, we present evidence for a small, even spin K- π+ amplitude that int…
A High Statistics Measurement of the Lambdac+ Lifetime
J. M. Link
A high statistics measurement of the Lambdac+ lifetime from the Fermilab fixed-target FOCUS photoproduction experiment is presented. We describe the analysis technique with particu…
