Beschreibungen/Notizen

• Fermilab experiment 871, HyperCP, is a search for direct CP violation in {xi} and {lambda} hyperon decays. A non-zero value in the asymmetry parameter A, defined in terms of the decay parameter products {alpha}{sub {xi}}{alpha}{sub {lambda}} and {alpha}{sub {xi}}-bar{alpha}{sub {lambda}}-bar, would be unambiguous evidence for direct CP violation. The first data-taking run finished at the end of 1997 and accumulated over one billion {xi}{sup -} and {xi}-bar{sup +} decays. A sensitivity in A of {approx_equal}10{sup -4} is expected. A review of CP violation in hyperon decays is given, the HyperCP detector is described, and the status of the data analysis is discussed.
