A Clifford-Gravity Based Cosmology, Dark Matter and Dark Energy

Authors: Carlos Castro

A Clifford-Gravity based model is exploited to build a generalized action (beyond the current ones used in the literature) and arrive at relevant numerical results which are consistent with the presently-observed de Sitter accelerating expansion of the universe driven by a very small vacuum energy density $ \rho_{obs} \sim 10^{ -120} (M_P)^4 $ ($ M_P $ is the Planck mass) and provide promising dark energy/matter candidates in terms of the $16$ scalars corresponding to the degrees of freedom associated with a $ Cl(3,1)$-algebra valued scalar field $ {\bf \Phi} $ in four dimensions.
