Restricted locality of quark-hadron duality in exclusive meson photoproduction reactions above the resonance region

Qiang Zhao, Frank E. Close

We show how deviations from the dimensional scaling laws for exclusive processes may be related to a breakdown in the locality of quark-hadron duality, i.e. the "restricted localit…

The Pentaquark $Θ^{+}$ in $n K^{+}$ and $p K_{S}^{0}$ , and its $Σ_{5}^{+}$ partner

Qiang Zhao, Frank E. Close

A systematic lowering in mass of strangeness ambiguous $p K_{S}^{0}$ peaks relative to the $n K^{+}$ is noted. We discuss how measurement of $γp\to Θ^+ K^0_S\to p K^0_S K^0_S \to pπ^+π^-π^…

Photoproduction of $Θ^{+}$ and other pentaquark states

Frank E. Close, Qiang Zhao

We present constraints on the {\it relative} photoproduction cross sections of positive parity pentaquark states, $Σ_{5}$ , $Λ_{5}$ , and $N_{5}$ , based on a minimum phenomenology gained i…

Glueball hunting in $e^{+} e^{-} \to J / ψ \to ϕ f_{0}$

Frank E. Close, Qiang Zhao

Building on recent work by Brodsky {\it et al.}, we advocate searching for glueball degrees of freedom in $e^{+} e^{-} \to J / ψ \to ϕ f_{0}$ at CLEO-c and BES.
