Charged Kaon K + → 3 π CP Violating Asymmetries vs ε ′
نویسندگان
چکیده
We present the next-to-leading order full results in Chiral Perturbation Theory for the charged Kaon K → 3π slope g CP violating asymmetries. We discuss the constraints that a measurement of these asymmetries would impose on the Standard Model results of ε K and search for new physics. We also study the kind of information that such measurement can provide on Im G8, Im (e GE) and higher order weak couplings.

Charged Kaon K → 3 π CP Violating Asymmetries 1
First full next-to-leading order analytical results in Chiral Perturbation Theory for the charged Kaon K → 3π slope g and decay rates CP-violating asymmetries are presented. We discuss the constraints that a measurement of these asymmetries would impose on the Standard Model calculations of ε K and the kind of information it can provide on Im G8, Im (e GE) and higher order weak couplings.

متن کاملCharged Kaon K → 3π CP Violating Asymmetries at NLO in CHPT
We give the first full next-to-leading order analytical results in Chiral Perturbation Theory for the charged Kaon K → 3π slope g and decay rates CP-violating asymmetries. We have included the dominant Final State Interactions at NLO analytically and discussed the importance of the unknown counterterms. We find that the uncertainty due to them is reasonable just for ∆gC , i.e. the asymmetry in ...

We describe possible kaon physics goals to achieve with a high luminosity Φ−factory. We motivate the relevance to improve the present bounds on CPT kaon physics quantities. Also, the interferometer machine Φ−factory is useful to study CP violating/conserving effects in kaon decays. Thus we investigate K → 3π amplitudes: charge asymmetries are interesting in charged kaon decays. In the case of n...

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 ...
