Search for $\Thetâ{++}$ Pentaquarks in the Exclusive Reaction $\gamma p\to K̂+K̂-p$ [electronic resource]

The reaction γp → K⁺K⁻p was studied at Jefferson Lab with photon energies from 1.8 to 3.8 GeV using a tagged photon beam. The goal was to search for a Θ{sup ++} pentaquark, a narrow doubly charged baryon state having strangeness S = +1 and isospin I = 1, in the pK⁺ invariant mass spectrum. No statis...

520 3 |a The reaction γp → K⁺K⁻p was studied at Jefferson Lab with photon energies from 1.8 to 3.8 GeV using a tagged photon beam. The goal was to search for a Θ{sup ++} pentaquark, a narrow doubly charged baryon state having strangeness S = +1 and isospin I = 1, in the pK⁺ invariant mass spectrum. No statistically significant evidence of a Θ{sup ++} was found. Upper limits on the total and differential production cross section for the reaction γp → K⁻Θ{sup ++} were obtained in the mass range from 1.5 to 2.0 GeV/c², with an upper limit of about 0.15 nb, 95% C.L. for a narrow resonance with a mass M{sub Θ{sup ++}} = 1.54 GeV/c². This result places a very stringent upper limit on the Θ{sup ++} width.
