N2 - The electronic structure of CeCoIn5, derived from a self-consistent calculation by means of a local density approximation (LDA) potential within the augmented plane wave framework, is used as an initial state. Considering this state, a mean field approximation from the multiband Hubbard Hamiltonian has been considered in order to include the strong correlation effects and a new self-consistent band structure has been determined. The results yield a spectrum where the splitting of the Hubbard bands is clearly displayed and the two-dimensional character of the electronic structure of this compound is obtained in a better way with respect to the structure attained with the simple LDA calculation.
