Abstract

We report results of the first search for the pentaquark P((c))over-bar-s which is predicted to be a doublet of states: P((c))over-bar-s(0)= [(c)over-bar-suud] and P((c))over-bar-s(-) = [(c)over-bar-sddu]. A search was made for the decay P((c))over-bar-s(0) --> phi pi p in datafrom upper limits at 90% confidence lever for the ratio of cross section times branching fraction of this decay to that for the decay D-s(+/-) --> phi pi(+/-). The upper limits vary between 0.022 and 0.046 forM(P((c))over-bar s)(0)) between 2.750 and 2.907 CeV/c(2), assuming a P((c))over-bar-s)(0) lifetime of 0.4 ps.
