Abstract

In this article, using the coupled-channel procedure, invariant mass spectra of in-flight kaon interaction on the deuteron target is investigated. In the calculation of interaction cross section, two processes as one- and two-interaction process are considered. The one-interaction process dominate at low values momenta of the incident kaon whereas the two-interaction contribution is not negligible at high values and both processes should be considered in the total cross section amplitude. By using analysis and considering of population, the sub-threshold theoretical invariant mass spectra are fitted to Braun’s data that the mass and width of are respectively extracted and . Although the present result, is fairly good agreement with the results of the chiral models, but does not consistent with the current value of the Particle Data Group.
