Abstract

A method of employing semileptonic \(K^{0}\)-meson decays is proposed. Combined with a time-dependent analysis of decay parameters of initially produced combination, it permits extracting \(K^{0}{-}\bar{K}^{0}\). These measurements could be applied to heavy-flavor physics problems—in particular, charm physics. A feasibility study for the strong-phase difference in charm decays is performed.
