Description
The HyperCP Collaboration at Fermilab is searching for CP violation in charged hyperon decays by comparing the angular decay distributions of protons and antiprotons from Ξ-→Λπ-, Λ→pπ- and Ξ-bar+→Λ-barπ+, Λ-bar→p-barπ+ decays. Using a hyperon data sample orders of magnitude larger than any other experiment has collected, we report a preliminary result AΞΛ=[-6.0±2.1(stat)±2.0(syst)]x10-4, from an analysis of the entire HyperCP data set of over one billion events.
