Mass splitting of neutral $B_{d,s}^{0}$ mesons in the framework of the minimal supersymmetric model

The effects of a minimal supersymmetric model with the Yukawa sector of the second type and explicit violation of $CP$ invariance in the Higgs potential occurring during the mixing of physical states in systems of neutral $B^0_{d,s}$ mesons are considered. The mixing parameter $\Delta m_{LS}$ is calculated in the limit of four-fermion approximation with the exchange of charged Higgs bosons ($H^\pm$). This study specifies data presented in [1] and establishes new constraints on
