CP Violation in Decays
The origin of CP violation remains a mystery in particle physics. So far, CP -odd signals have been observed only in the kaon systems. To determine the source and nature of CP violation, it is necessary to observe it in several di erent processes. For a number of years theoretical e orts have been made to study it in the weak decays of hyperons belonging to the baryon octet [1{3]. Here, we pres...

متن کاملCP Violation in Hyperon Decays
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 B Decays
In the near future, we will have the first significant experimental measurements of CP violation in B decays. These measurements will easily test crucial questions such as whether the Standard Model Kobayashi-Maskawa phase plays a dominant role in CP violation or whether CP is an approximate symmetry in nature. We explain the different types of CP violation in B decays, and the usefulness of me...
متن کاملCp Violation in Kaon Decays ∗
We review the Standard Model predictions of CP violation in kaon decays. We present an elementary introduction to Chiral Perturbation Theory, four–quark effective hamiltonians and the relation among them. Particular attention is devoted to K → 3π, K → 2πγ and K → πf̄f decays. To appear in International Journal of Modern Physics A ∗ Work supported in part by HCM, EEC–Contract No. CHRX–CT920026 (E...
