An. Ivanov et al., ON THE S-WAVE PI-D-SCATTERING LENGTH IN THE RELATIVISTIC FIELD-THEORYMODEL OF THE DEUTERON, ZEITSCHRIFT FUR PHYSIK A-HADRONS AND NUCLEI, 358(1), 1997, pp. 81-84
The S-wave scattering length of the strong pion-deuteron (pi D) scatte
ring is calculated in the relativistic field theory model of the deute
ron suggested in [1,2]. The theoretical result agrees well with the ex
perimental data. The important role of the Delta-resonance contributio
n to the elastic pi D-scattering is confirmed.
