Measurement of ε′/ε from the NA48 experiment
نویسنده
چکیده
Using data collected in 1998 by the NA48 experiment, a preliminary measurement of the direct CP violation parameter Re (ε/ε) is here presented, together with a discussion of the experimental method, data analysis and systematic studies. The result is Re (ε/ε) = (12.2± 4.9) × 10, and combined with the previously published NA48 result (based from data collected in 1997) gives Re (ε/ε) = (14.0± 4.3)× 10.

Measurement of Direct Cp Violation by Na48
The NA48 experiment at the CERN SPS aims to search for direct CP /violation in the K system through the measurement of Re(ε/ε) with high accuracy. In 1999 the NA48 collaboration has published its first measurement based on 1997 data. The final result based on 1998 and 1999 data is presented in this article. The result, combined with 1997 data, Re(ε/ε) = (15.3 ± 2.6) × 10, definitely established...
متن کاملMeasurement of the direct CP violation by NA48 experiment at CERN
The NA48 experiment at the CERN SPS accelerator aims to measure Re(ε′/ε), the direct CP violation parameter in K → 2π decays, to the precision of 2 × 10−4. In the year 1999, the NA48 collaboration has published its first measurement based on the 1997 data. The presented result is a preliminary measurement from data collected in the 1998 run which contain 2.5 times more KL → 2π decays than the 1...

The direct CP violation parameter Re(ε′/ε) has been measured from two-pion 12 decays of neutral kaons by the NA48 experiment at CERN SPS. The analysis 13 of a new data sample, collected in 2001 under different conditions compared 14 to earlier years (1997–99), provide the result: Re(ε′/ε) = (13.7 ± 3.1)× 10−4. 15 Combining this result with that published from 1997–98-99 data, we obtain 16 an ov...
