Investigation of the mixed entrance channels of resonance on the invariant mass spectrum, in Kaon-Proton interaction at  GeV/c

In this paper, to solve the current ambiguity in the entrance channels  or  of  resonance state for Kaon-proton interaction at 4.2 Gev/c, a mixture of transition matrix elements for entrance channels of and  in the resonance formation of have been used. A comparison of the theoretical invariant mass spectra with the totally Hemingway’s experimental data indicates that in this interaction, the  channel is the dominant entrance channel. In the following, using the  analysis method, the mass and width of the  resonant state are respectively obtained  and that are in a good agreement with the present values of mass and width of the in particle data group (PDG).
