Study of Entangled K-meson and Its Decoherence

In this paper, entangled K-meson model and decoherence phenomenon in thesystem is studied. Using Lindblad equation, dynamical equation of systemthat interacts with the environment obtained. We find that non-Hermitian Hamiltonian ofthe system makes completely positive trace-preserving map (CPT-map) on space ofdensity matrix does not satisfy trace preserving properties. also purity densitymatrix can be less than 1=d which property purity. From dynamicalequation, parameters related to system, parameter (λ) andeffective (ζ), are determined. Standard Least-Squares method,we obtain ζ = 0; 13±0; 865. This result accordance references use effectivevariance method, 13±+0 -0;;16 15. show 15 corresponds referencesresult, λ (1; 84±+2 -2;;50 17) × 10-12 MeV. The value both close zero relativeto 1 or ! 1. It means interaction between doesnot affect significantly. Therefore, quantum properties theentanglement strangeness preserved.
