Abstract:

We show tha effects of dibaryon resonances can be clearly seen in the data on the differential cross section of πd elastic scattering. Giving the formulation of the Glauber model with the resonance formation term in πd direct channel in detail and analyzing all the data presently available by this model, we find that at least two resonances are needed in πd direct channel in order to explain the data. One of them may be 3F3 (2.25 GeV) state of two nucleons which was found at Argonne and the other has mass value around 2.5 GeV. The data are not enough to determine the spin-parity of the latter but 0+ seems somewhat preferable. The branching ratios of the resonances into πd system are also given.
