A New Measurement of the Cascade(c)+ Lifetime
FOCUS Collaboration
A precise determination of the charm-strange baryon Cascade(c)+ lifetime is presented. The data were accumulated by the Fermilab high-energy photoproduction experiment FOCUS. The m…
Reconstruction of Vees, Kinks, 's, and 's in the Focus Spectrometer
The FOCUS Collaboration
We describe the various techniques developed in the Fermilab Wideband Experiments, E687 and FOCUS, to reconstruct long-lived states. The techniques all involve modifications to sta…
Search for CP Violation in the decays D+ -> K_S pi+ and D+ -> K_S K+
The FOCUS Collaboration
A high statistics sample of photo-produced charm from the FOCUS(E831) experiment at Fermilab has been used to search for direct CP violation in the decays D+->K_S pi+ and D+ -> K_S…
Cerenkov Particle Identification in FOCUS
The FOCUS Collaboration
We describe the algorithm used to identify charged tracks in the fixed-target charm-photoproduction experiment FOCUS.
Measurement of the relative branching ratio BR(Ξ_c^+ \to p^+ K^-π^+)\BR(Ξ_c^+ \to Ξ^- π^+ π^+)
The FOCUS collaboration, J. M. Link
We report the observation of the Cabibbo suppressed decay Ξ_c^+ \to p K^-π^+ using data collected with the FOCUS spectrometer during the 1996--97 Fermilab fixed target run. We find…
