The $J = 3/2$ $Θ^{*}$ partner to the $Θ (1540)$ baryon

J. J. Dudek, F. E. Close

If the exotic baryon $Θ (1540)$ is $u d u d s ˉ$ with $J^{P} = 1/2^{+}$ , we predict that there is a \10bar with $J^{P} = 3/2^{+}$ containing a $Θ^{*} (1540 - 1680)$ . The width $Γ(Θ^* \to KN)…

The "forbidden" decays of hybrid mesons to $π ρ$ can be large

F. E. Close, J. J. Dudek

The observation of $π_{1} (1600) \to π ρ$ is shown in the flux-tube model to be compatible with this state being a hybrid meson with branching ratio to this channel $\sim 30$ . The $πρ…

Symmetry breaking and quark-hadron duality in structure functions

F. E. Close, W. Melnitchouk

We identify conditions under which a summation over nucleon resonances can yield, via quark-hadron duality, parton model results for electromagnetic and neutrino structure function…
