We present an extension of the minimal split supersymmetry model, which iscapable of explaining the baryon asymmetry of the Universe. Instead of MSSM westart from NMSSM and split its spectrum in such a way that the low energytheory contains neutral particles, in addition to the content of minimal splitsupersymmetry. They trigger the strongly first order electroweak phasetransition (EWPT) and provide an additional source of CP-violation. In thismodel, we estimate the amount of the baryon asymmetry produced during EWPT,using WKB approximation for CP-violating sources in diffusion equations. Wealso examine the contribution of CP-violating interactions to the electron andneutron electric dipole moments and estimate the production of the neutralinodark matter. We find that both phenomenological and cosmological requirementscan be fulfilled in this model.Comment: 31 pages, 9 figures, typos correcte
