The SELEX experiment at Fermilab Available to Purchase

The SELEX experiment (Segmented Large-X Spectrometer) has been taking data in the 1996–7 Fermilab fixed-target run. The experiment uses a 650 GeV/c negative beam which is 50% $Σ−,$ 50% $π−.$ The primary purpose is to study the production and properties of charmed and charm-strange baryons, but there is also a wide program of other physics topics. The present status of the experiment and preliminary analysis are presented.
