CPT tests in the neutral kaon system by FNAL E773
- University of Chicago, Chicago, Illinois 60637 (United States)
The FNAL experiment E773 has measured the phases {Phi}{sub +{minus}}=43.35{degree}{plus_minus}0.70{degree}{plus_minus}0.79{degree} and {Phi}{sub 00}{minus}{Phi}{sub +{minus}}=0.67{degree}{plus_minus}0.85{degree}{plus_minus}1.1{degree} of the CP violating parameters {eta}{sub +{minus}} and {eta}{sub 00} in the decay of neutral kaons into two charged or neutral pions. These preliminary results test the CPT symmetry and show no evidence for a violation. In addition we present a preliminary measurement of {Delta}{ital m}=(0.5286{plus_minus}0.0029{plus_minus}0.0022){center_dot}10{sup {minus}10} {h_bar}/{ital sec} and {tau}{sub {ital S}}=(0.8929{plus_minus}0.0014{plus_minus}0.0014){center_dot}10{sup {minus}10} {ital sec}. The first errors are statistical and the second errors are systematic for above results. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
