An explanation why the Theta+ is seen in some experiments and not in others
Ya. Azimov, K. Goeke, I. Strakovsky
To understand the whole set of positive and null data on the Theta+(1530) - production, we suggest the hypothesis that multiquark hadrons are mainly generated from many-quark state…
K*-couplings for the antidecuplet excitation
Ya. Azimov, V. Kuznetsov, M. V. Polyakov +1
We estimate the coupling of the K* vector meson to the N-->Theta+ transition employing unitary symmetry, vector meson dominance, and results from the GRAAL Collaboration for eta ph…
Search for Higher Flavor Multiplets in Partial Wave Analyses
Ya. I. Azimov, R. A. Arndt, I. I. Strakovsky +2
The possible existence of higher multi-quark flavor multiplets of baryons is investigated. We argue that the S-matrix should have poles with any quantum numbers, including those wh…
Present status of the nonstrange and other flavor partners of the exotic Theta+ baryon
I. I. Strakovsky, R. A. Arndt, Ya. I. Azimov +2
Given the existing empirical information about the exotic Theta+ baryon, we analyze possible properties of its SU(3)F-partners, paying special attention to the nonstrange member of…
Resonances, and mechanisms of Theta-production
Ya. I. Azimov, I. I. Strakovsky
After explaining necessity of exotic hadrons, we discuss mechanisms which could determine production of the exotic Theta-baryon. A possible important role of resonances (producing…
Decay properties of new D-mesons
Ya. I. Azimov, K. Goeke
We consider radiative and pionic decays of the new D_s-mesons in the framework of a phenomenologically motivated approach. Present data on ratios of the two kinds of decays can be…
