SUPERSYMMETRIC MODEL WITH CP VIOLATION. 3. CP VIOLATION IN THE HIGGS SECTOR

The effective potential of the two-Higgs-doublet sector of the Minimal Supersymmetric Model (MSSM) is considered. The evolution of the parameters of the two-doublet scalar potential with explicit violation of the CP invariance, the boundary conditions for which are taken on the scale of supersymmetry breaking M_SUSY is studied, and the analysis of the effective Higgs self-couplings is carried out. The diagonalization conditions of the effective two-doublet potential in a local minimum are shown depend on the complex parameters of the Higgs interaction with scalar t and b quarks. It is demonstrated, that the CP violating phases in the CKM matrix and in the generalized two-doublet potential of the Higgs sector (THDM) with complex parameters and vacuum expectation values are independent sources of CP violation in the charge currents.

THE EFFECT OF REFERENCE AND READING WAVES DIVERGENCE ON ANGULAR SELECTIVITY OF AMPLITUDE DYNAMIC HOLOGRAM IN THE "TWO-LEVEL" MEDIUM

The angular dependence of the diffraction efficiency of the dynamic hologram in the "two-level" nonlinear medium taking account of reading (reference) wave divergence is studied. The expression of angle band width of the dynamic hologram via its optimum thickness and angular divergence of the reading wave is obtained. The range of applicability of this expression is then determined.
