Abstract
The Kd reactions are considered in the impulse approximationwithNN final-state interactions (FSI) taken into account. Realistic parameters for the KN phase shifts are used. The “quasi-elastic” energy region, in which the elementary KN interaction is predominantly elastic, is considered. The theoretical predictions are compared with the data on the K+d → K+pn, K+d → K0pp, K+d → K+d, and K+d total cross sections. The NN FSI effect in the reaction K+d → K+pn has been found to be large. The predictions for the Kd cross sections are also given for slow kaons, produced from ϕ(1020) decays, as the functions of the isoscalar KN scattering length a0. These predictions can be used to extract the value of a0 from the data.
