Abstract

The measurement of the charge symmetry in KL semileptonic decays based on 298× 106 was reported. A value of δL=[3322∓ 58(stat) ∓47 (syst)] × 10-6 was measured, which was in agreement with previous measurements and 2.4 times more precise than current best published results. The result places more stringent limits on CPT and δS=δQ violation in the neutral kaon system.
