Fermilab experiments E731, E773, E799, and E832 are a series of experiments to investigate the physics of CP violation, CPT violation, and rare decays of the neutral kaon system. E731 finished data taking in 1988, during past year the full data set analysis was completed and yielded ([var epsilon][prime]/[var epsilon])[sub 2[pi]]=(7.4 [plus minus] 5.2 [stat] [plus minus] 2.9 [syst]) [times] 10[sup [minus]4] . The value favors a high top ark mass value within the Standard Model. E773 tests CPT violation by determining ([Delta][phi])[sub 2[pi]] with an accuracy of about 0.5[sup 0]. Data were taken during the last Fermilab Fixed Target run period between September and November 1991. It is anticipated the data analysis will be finished within a year. E799, with the primary goal of observing direct Cp Violation via searching for the rare decay K[sub L][yields] [pi][sup 0] l [sup +]l[sup [minus]] (where l = e, [mu] [nu]) took test data between November 1991 and January 1992 (Phase 1). Some preliminary results are shown here. E799 (Phase II) and E832 (a follow up experiment of E731) are scheduled to take data after the current Fermilab collider run with a new facility and detector.

This report discusses the progress on the measurement of the direct CP violation parameter {var_epsilon}′/{var_epsilon} and the rare KL decay. The progress has been as follows: (A) results from the complete E731 data set which was collected in the 1987/88 fixed target run; preparations for and the taking of the data for (B) E773 (CPT symmetry test) and (C) E799 (rare decay study); and finally (D) R&D for a new detector to further study {var_epsilon}′/{var_epsilon} and rate decays.

E731 finished data taking in 1988, during past year the full data set analysis was completed and yielded ({var_epsilon}′/{var_epsilon}){sub 2?}=(7.4 ± 5.2 [stat] ± 2.9 [syst]) × 10−4 . The value favors a high top ark mass value within the Standard Model. E773 tests CPT violation by determining (??){sub 2{pi}} with an accuracy of about 0.5°. Data were taken during the last Fermilab Fixed Target run period between September and November 1991. It is anticipated the data analysis will be finished within a year. E799, with the primary goal of observing direct Cp Violation via searching for the rare decay K{sub L}→ {pi}° l l− (where l = e,??) took test data between November 1991 and January 1992 (Phase 1).
