Since the recently reported giant isotope effect on T * (Lanzara A et al 1999 J. Phys.: Condens. Matter 11 L541 and Rubio Temprano D et al 2000 Phys. Rev. Lett. 84 1990) could be consistently explained within an anharmonic spin-charge-phonon interaction model, we consider here the role played by stripe formation on the superconducting properties within the same model. This is a two-component scenario and we recast its basic elements into a BCS effective Hamiltonian. We find that the stripe formation is vital to high- T c superconductivity since it provides the glue between the two components to enhance T c to the unexpectedly large values observed experimentally.
