A Measurement of the KL Charge Asymmetry
The KTeV Collaboration, A. Alavi-Harati
Abstract
We present a measurement of the charge asymmetry δL in the mode KL πeν based on 298 million analyzed decays. We measure a value of δL = (3322 58(stat) 47(sys))· 10-6, in good agreement with previous measurements and 2.4 times more precise than the current best published result. The result is used to place more stringent limits on CPT and ΔS = ΔQ violation in the neutral kaon system.
