It is shown that the anomalously low-lying Roper states cannot be assigned as pentaquarks with the scalar diquark - scalar diquark - antiquark structure as suggested by Jaffe and Wilczek.

Notes on exotic anti-decuplet of baryons
We emphasize the importance of identifying non-exotic SU(3) partners of the Theta^+ pentaquark, and indicate possible ways how to do it. We also use the soliton picture of baryons to relate ReggeonExpand
The Mass structure of SU(3) baryon antidecuplet and pion muon mass difference
We show that the mass intervals among the pentaquark baryons $\Theta^{+}$, $N^{*}(1685)$ and $\Xi_{3/2}^{-}$ proposed to be the members of the SU(3) antidecuplet are exact integral multiples of theExpand
Spatially improved operators for excited hadrons on the lattice
We present a new approach for determining spatially optimized operators that can be used for lattice spectroscopy of excited hadrons. Jacobi smeared quark sources with different widths are combinedExpand
Investigating the parity of the exotic Θ + baryon from kaon photoproduction
Based on the hadronic model with the gauge prescription suggested by Ohta and Haberzettl, we investigate the possibility of determining the parity state of the {theta}{sup +} baryon using photonExpand
