Measurement of the CP Violation Parameter $$\eta+ - \gamma$$
- Rutgers U., Piscataway
This dissertation describes the measurement of the CP violation parameter $$\eta + - \gamma$$ in a neutral kaon experiment, E773, at Fermilab. The parameter $$\eta + - \gamma$$ characterizes CP violation in ·the decay $$K_L \to \pi^+ \pi^- \gamma$$. Kaon decays into $$\pi^+\pi^-$$- collected simultaneously were used for normalization. The result is $$\mid\eta+-\gamma\mid$$ = (2.359 ± 0.062 .. stat ± 0.040.sys) X $$10^{-3}$$ with a phase $$\phi + - \gamma$$ = ( 43.8 ± 3.5,stat ± 1.9 sys )$$^{\circ}$$. The prediction that $$\eta + - \gamma$$ should be very close to $$\eta + -$$ is supported by this result.
