Charm physics results from SELEX Available to Purchase

The SELEX experiment (ET781) [1] at Fermilab is a new fixed target multistage spectrometer with high acceptance for forward interactions and decays. It took data in 1996–97 with 600 GeV $Σ−,$ $π−$ and 540 GeV p beams, collecting large sample of charm decays. Preliminary results on charm—anticharm production asymmetries, $Λc+$ production $xF$ dependence in different beams, $Λc+$ lifetime, and the first observation of the Cabibbo-suppressed decay $Ⅺc+→pK−π+$ are presented.
