Description
Summary:The Λ*‎ resonance has been studied and investigated both theoretically and experimentally for decades‎. ‎The purpose of this paper is to study the mass and width of Λ* resonance state theoretically by calculating the T-matrix using a generalized optical potential with a Yukawa-type separable potential‎. ‎In the current calculation, the formation of Λ* in the K-d → Λ*‎ + ‎n → (Σπ)0 + n reaction is studied and the results of the analysis are fitted to the experimental data of E-31 carried out at J-PARC accelerator which is related to the collision of negative kaon of 1GeV/c momentum with liquid deuteron and according to the best fit‎, ‎mass and width of this resonant state calculated as MΛ* =1419 ± 2.4 MeV/c2 and , ‎respectively.
