We report a search for narrow resonances, produced in p (p) over bar collisions at root s = 1.96 TeV, that decay into muon pairs with invariant mass between 6.3 and 9.0 GeV/c(2). The data, collected with the CDF II detector at the Fermilab Tevatron collider, correspond to an integrated luminosity of 630 pb(-1). We use the dimuon invariant mass distribution to set 90% upper credible limits of about 1% to the ratio of the production cross section times muonic branching fraction of possible narrow resonances to that of the (sic)(1S) meson.
We thank the Fermilab staff and the technical staffs of the participating institutions for their vital contributions.
