Direct CP Violation in Neutral Kaon Decays
نویسنده
چکیده
Abstract. The final result is presented of the NA48 experiment, performed at the CERN SPS neutral kaon beams, on the direct CP violation parameter Re(ε′/ε), as measured from the decay rates of neutral kaons into two pions. The data collected in years 1997-2001 yield the evidence for the direct CP violation with Re(ε′/ε) = (14.7± 2.2) × 10. Description of experimental method and systematics, comparison with the corresponding FNAL result and discussion of some implications for theory are given.

Review 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 ...
متن کاملComments on CP, T and CPT Violation in Neutral Kaon Decays
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 AT measured by CPLEAR could be solely due to CPT violation, confirming that t...

متن کاملThe Search for Cp Violation in Hyperon Decays
Searches for experimental manifestations of CP violation have born much fruit in recent years with the discovery of direct CP violation and the first evidence of CP violation outside of the neutral kaon system. Nevertheless we still know little about CP violation: its origin remains a mystery and there is little hard evidence that it is the sole province of the standard model. Searches for CP v...
متن کاملKTeV Results: Re(ǫ ′ /ǫ) and Rare Decay Results
The KTeV physics program encompasses many goals including a precision measurement of the direct CP violation parameter Re(ǫ ′ /ǫ) in KS,L → ππ decays, and studies of rare neutral kaon decays. The KTeV detector collected data during the Fermilab fixed-targed runs of 1996-97 and 1999. This article focuses on the precision measurement of the direct CP violation parameter Re(ǫ ′ /ǫ) using the 1996-...
