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).

Abstract

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.
