Effects of minimal supersymmetry standard model in neutral $K^0$ meson mixing

Mixing of neutral $K^0$ mesons is studied in the framework of the minimal supersymmetric model (MSSM) with a Yukawa type II sector and explicit violation of $CP$ invariance in the Higgs potential. Mixing parameters$\Delta m_{LS}$ and $\varepsilon$ are calculated in the limit of the four-fermion approximation with charged Higgs boson exchange. This work specifies the data presented in [1] more precisely and, taking into account the influence of new contributions on the above observables, proves the small degree of supersymmetric effects for a system of $K^0$ mesons.
