Abstract: (APS)
A careful search has been made for possible CP-nonconserving differences between K+→π+π0γ and K−→π−π0γ decays. In a sample of over 4000 completely reconstructed decays in the charged-pion kinetic-energy interval of 51 to 100 MeV, the asymmetry is 0.005 ± 0.020, with a systematic uncertainty of ± 0.022, indicating no evidence for a CP-invariance violation. This result, combined with that obtained from the sum spectrum, suggests that the direct emission is largely magnetic dipole.- k+: decay modes
