THE STRUCTURE CALCULATION OF K pp WITH Λ * p MODEL
Abstract
- The purpose of this research is to investigate the structure of K- pp system by using Λ p * model, where * Λ is a resonance state of K- p system. To determine the binding energy of this system, Schrödinger equation is solved in two body system, which consists of * Λ and proton. In our calculation, the Gaussian basis wave function is used to solve the Schrödinger equation. Phenomenologically constructed potential of Λ p * interaction is used in this calculation. The experimental value for the binding energy of * Λ is 27 MeV. By using theYamazaki and Akaishi phenomenological potential, the calculated result of the binding energy of K- pp system from the Λ p * threshold is 21.17 MeV and level width is 61 MeV. The binding energy of K- pp system from (K- + p + p) threshold is ( 21.17 + E Λ* ) 48.17MeV. .By using the DISTO experimental data, the calculated binding energy for K- pp system from Λ*p threshold is 78.0457 MeV and level width is 118.4 MeV. The binding energy of K- pp system from (K- + p + p) threshold is ( 78.04 E Λ*) = 105.04 MeV. Thus, the calculated results for binding energy of K- pp system are in good agreement with the calculated result of YA and experimental result of DISTO.
