Multiwire proportional chambers in M1 and M3 spectrometers of charmed baryon experiment (E781) at Fermilab
The status of the multiwire proportional chambers in the FERMILAB E781 experiment and a general description of the readout system are given. This essay will describe the system of multiwire proportional chambers (MWPC) that are part of the Fermilab experiment E781 setup. Multiwire proportional chambers are often used in particle physics experiments because they can determine the position of charged particles very accurately (less than a millimeter). The E781 experiment which is also called SELEX (SEgmented LargE-X) is a spectrometer designed to study the production and decay of charmed baryons. MWPCs are part of the 3-stage charged particle spectrometer (Figuremore » -
First charm baryon physics from SELEX(E781)
We present preliminary results on various aspects of charm baryon studies at the 1996-1997 fixed target experiment of Fermilab studying charm produced from incident {Sigma}{sup -}, proton, and {pi}{sub -} beams at 600 GeV. First results include the comparison of hadroproduction asymmetries for {Lambda}{sub c}{sup +} production from the 3 beams as well xF distributions and the first observation of the Cabbibo-suppressed decay {Xi}{sub c}{sup +} {yields} pK{sup -}{pi}{sup +}. The relative branching fraction of the Cabbibo-suppressed mode to the 3-body Cabbibo-favored modes is also presented. -
A proposal to construct SELEX - segmented large-x baryon spectrometer
Heavy flavor experiments currently in progress at e{sup +}e{sup -} colliders or in the fixed target programs at CERN and Fermilab are aimed at collecting large samples (> 10,000 reconstructed events) of charmed events. These experiments will provide a great deal of information about charmed meson systems, but the expected yield of charmed baryons is not large--10% or less of the sample size. The most detailed study of the charm strange baryon {Xi}{sub c}{sup +} comes not from a large-statistics central production experiment at high energy but rather from a 20-day run at modest beam flux in the CERN hyperonmore »
