Cp Violation in Kaon Decays ∗
نویسنده
چکیده
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.

متن کاملFlavor Physics in Kaon Decays
Kaon physics has a glorious history. Parity violation, CP violation, GIM mechanism, CKM mechanism, Determination of Standard Model (SM) parameters, Hadronic physics all have imprints of kaon physics. Kaon physics still plays an important role in particle physics. Some of the main interests today in kaon physics are: The studies of CP violation and rare decays; Determination of SM parameters; Lo...
متن کاملCP 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 کاملEstablishment of Cp Violation in B Decays
■ Abstract Until recently, CP violation had been observed only in kaon decays. In order to conclusively interpret CP violation and test whether it can be explained in the framework of the Cabibbo-Kobayashi-Maskawa matrix, two asymmetric B factories, KEK-B and PEP-II, were constructed in the past decade. Recent measurements with the two detectors at these B factories clearly established large CP...
متن کاملReview of the NA48 CP violation measurements with neutral and charged kaons
The main results on the CP violation measurements with neutral and charged kaons from the NA48 experiment at the CERN SPS are reviewed in this paper. The direct CP violating parameter Re(ε′/ε) has been measured by NA48 from the decay rates of neutral kaons into pion pairs. The final result, based on the data collected in 1997, 1998, 1999 and 2001, clearly established the existence of direct CP ...
