Abstract
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 t he 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 a n upper limit for the branching ratio of K-L --> pi(o)nu<(nu)over bar> to b e < 5.9 x 10(-7) at the 90% confidence level.
