Available in PDF, EPUB and Kindle. Book excerpt: This report discusses the progress on the measurement of the direct CP violation parameter {var epsilon}(prime)/{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}(prime)/{var epsilon} and rate decays.
