SUPERSYMMETRIC MODEL WITH EXPLICIT CP VIOLATION. 2. PAIR-PRODUCTION OF THE NEUTRAL HIGGS BOSONS AT LHC

The cross sections of the lightest neutral Higgs bosons pair-production in the gluon-gluon collisions are calculated in the framework of the general two-Higgs-doublet model (THDM). Comparative analysis with the cross sections obtained in the minimal supersymmetric standard model (MSSM) is performed. It is shown that the values of differential cross sections calculated in THDM and MSSM are substantially different in some regions of the parameter space. The Appendix contains the new algorithms of calculation for Passarino-Veltman-'t Hooft scalar one-loop integrals which have been used for the evaluation of Higgs boson pair-production cross sections.

WEIGHT FUNCTION OF THE VOLUMETRIC DYNAMIC HOLOGRAM IN A DYE SOLUTION

The dependence of the weight function width on the layer thickness, radiation intensity and dye parameters for the dynamic hologram recording in a dye solution modelled by the three-level energy scheme is obtained.
