Resumen

EL- NABULSI, Ahmad Rami. Effective cosmology a la Brans-Dicke with a non-minimally coupling massive inflaton field interacting with minimally coupling massless field. Braz. J. Phys. [online]. 2010, vol.40, n.3, pp. 273-282. ISSN 0103-9733.  http://dx.doi.org/10.1590/S0103-97332010000300003.

We discuss an effective cosmology a la Brans-Dicke with two interacting scalar fields: a non-minimally coupling massive inflaton Higgs-like scalar field Φ interacting with a minimally coupling massless scalar field χ. Several features are observed and discussed in some details.

Palabras llave : Interacting scalar fields; non- minimal and minimal couplings; quintessence.
