摘要：

We report on a search for the decay K-L --> pi(o)nu<(nu)over bar>, carried out as a part of E799-II, a rare K-L decay experiment at Fermilab. Within the standard model, the K-L --> pi(o)nu<(nu)over bar> decay is dominated by direct CP violating processes, and thus an observation of the decay implies confirmation of direct CP violation. No events were observed, and we set an upper limit for the branching ratio of K-L --> pi(o)nu<(nu)over bar> to be < 5.9 x 10(-7) at the 90% confidence level.
