Search for Rare and Forbidden 3-body Di-muon Decays of the Charmed Mesons D+ and Ds+
FOCUS Collaboration
Using a high statistics sample of photo-produced charm particles from the FOCUS experiment at Fermilab, we report results of a search for eight rare and Standard-Model-forbidden de…
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…
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…
Performance of prototype BTeV silicon pixel detectors in a high energy pion beam
J. A. Appel, M. Artuso, J. N. Butler +21
The silicon pixel vertex detector is a key element of the BTeV spectrometer. Sensors bump-bonded to prototype front-end devices were tested in a high energy pion beam at Fermilab.…
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…
Beam Test of BTeV Pixel Detectors
J. C. Wang, J. A. Appel, M. Artuso +20
The silicon pixel vertex detector is one of the key elements of the BTeV spectrometer. Detector prototypes were tested in a beam at Fermilab. We report here on the measured spatial…
