Production of the pentaquark exotic baryon Ξ 5 in KN scattering : KN → K Ξ 5 and KN → K ∗ Ξ 5

Abstract We investigate the production of the newly found pentaquark exotic baryon Ξ5 in the KN → KΞ5 and KN → KΞ5 reactions at the tree level. We consider the both positiveand negativeparities of the Ξ5. The reactions are dominated by the sand u-channel processes, and it is observed that the resulting cross sections are very much dependent on the parity of Ξ5 and on the type of form factor. We...

Ξ -ζ Relation

In this note we prove a relation between the Riemann Zeta function, ζ and the ξ function (Krein spectral shift) associated with the Harmonic Oscillator in one dimension. This gives a new integral representation of the zeta function and also a reformulation of the Riemann hypothesis as a question in L1(R). ∗Part of talk presented at the Conference on Harmonic Analysis, 13-15 March 1997, Ramanuja...

Glueball Interpretation of ξ(2230)

On the basis of the results of ξ(2230) → π+π−, pp̄ and KK̄, measured by the BES Collaboration in radiative J/ψ decays, combined with the upper limit of Br(ξ → pp̄)Br(ξ → KK̄), measured by PS185 experiment, we argue that the distinctive properties of ξ(2230), the flavor-symmetric decays and the narrow partial decay widths to ππ andKK̄ as well as its copious production in radiative J/ψ decay, would st...
