CP Asymmetry in the Ξ Hyperon Sector
نویسندگان
چکیده
The Standard Model of particle physics has achieved great success in describing the fundamental particles and their interactions, but there are still some issues that have not been addressed yet. One key puzzles is to figure out why so much more matter than antimatter Universe, regarded as CP asymmetry. Ξ hyperon with strangeness S=−2, sometimes so-called doubly-strange baryon, can provide information probe asymmetry antimatter. In this review, we discuss studies decay at E756, HyperCP BESIII experiments.

In this talk we review the status of the theoretical estimates for CP violating asymmetries in non-leptonic hyperon decays. ∗Invited talk presented at HQ94, Oct.7-10, 1994, Charlottesville, Virginia. 1 – The Decay Λ → pπ− The reaction Λ → pπ will be used as an example to set up the model independent formulation of the CP odd observables in non-leptonic hyperon decays of the form Bi → Bfπ. In th...
متن کاملCP violation in Hyperon decays
The CP properties in hyperon decays are briefly reviewed. We discuss the general phenomenology and define CP odd observables in hyperon decays. With these observables, we discuss the predictions of some models and their observational potential.

The Hyperon-CP-Violation working group at the p2000 Workshop met together with the Beta-Decay working group. After brie y introducing the physics, I summarize the workinggroup discussions relevent to CP violation. The working group sketched issues that need to be explored in designing a hyperon CP-violation experiment that might achieve 10 5 sensitivity for the CP asymmetry A , one order of mag...
