Abstract
In the context of the pre-Big Bang scenario of string cosmology, we propose a modified equation for the evolution of the tensor perturbations, which includes the full contribution of possible higher-order curvature and coupling corrections required to regularise the background evolution. We then discuss the high-frequency branch of the spectrum of primordial gravitons.
