چکیده
The recent results on the CP violating parameters Re(ε/ε) and ∆φ ≡ φ00 − φ+− reported by the KTeV Collaboration are analyzed with a view to constrain CP , T and CPT violations in a decay process. Combining with some relevant data compiled by the Particle Data Group, we find Re(ε2− ε0) = (0.85±3.11)×10−4 and Im(ε2− ε0) = (3.2±0.7)×10−4, where Re(εI) and Im(εI) represent respectively CP/CPT and CP/T violations in decay of K0 and K0 into a 2π state with isospin I.

CP , T and CPT Violations in the K 0 − K 0 System — Present Status —
Possible violation of CP , T and CPT symmetries in the K0−K0 system is studied in a way as phenomenological and comprehensive as possible. For this purpose, we first introduce parameters which represent violation of these symmetries in mixing parameters and decay amplitudes in a convenient and well-defined way and, treating these parameters as small, derive formulas which relate them to the exp...
متن کاملComments on CP , T and CPT Violation in Neutral Kaon
We comment on CP, T and CPT violation in the light of interesting new data from the CPLEAR and KTeV Collaborations on neutral kaon decay asymmetries. Other recent data from the CPLEAR experiment, constraining possible violations of CPT and the ∆S = ∆Q rule, exclude the possibility that the semileptonic-decay asymmetry A T measured by CPLEAR could be solely due to CPT violation, confirming that ...
متن کاملSymmetry Be Tested With K 0 vs K̄ 0 → π + π − π 0 Decays ?
We show that the CP-violating effect in K vs K̄ → πππ decays differs from that in KL → π π, KL → π π or the semileptonic KL transitions, if there exists CPT violation in K-K̄ mixing. A delicate measurement of this difference in the KTeV experiment and at the φ factory will provide a new test of CPT symmetry in the neutral kaon system. PACS number(s): 11.30. Er, 13.25. Es, 14.40.

Kaon decays continue to provide invaluable information about the approximate discrete symmetries of nature. CP-violation inK L → ππ[1], originating in the K −K mass matrix, was discovered nearly forty years ago and direct CP-violation in K-decays has been unambiguously established[2, 3, 4], through a recent remeasurement of Re (ǫ′/ǫ) = (28.0±3.0±2.8)×10−4 by the KTeV collaboration[4]. KTeV has ...
