We present precise measurements of CP and CPT symmetry based on the full
dataset of K to 2pi decays collected by the KTeV experiment at FNAL. We measure
the direct CP violation parameter Re(epsilon'/epsilon) = (19.2 pm 2.1)x10-4. We
also report the KL-KS mass difference, the KS lifetime, the phase of epsilon,
and the phase difference (phi00)-(phi+-). These results are consistent with
other experimental results and with CPT symmetry.Comment: 10 pages, 19 figures. To be published in the proceedings of DPF-2009,
