Abstract
We report on a search for and (and charge conjugate) decays in collisions at using of data collected by the CDF II experiment at the Fermilab Tevatron Collider. Data were collected using a track trigger that has been optimized to select tracks belonging to a secondary vertex that is typical of two-body charmless decays of -flavored hadrons, including baryons. As no signal was observed, we set the upper limits on the branching fraction , where is or , of at 90% C.L. and at 95% C.L.
