Resumen

The value of the tensor-to-scalar ratio r in the region allowed by the latest Planck 2015 measurements can be associated to a large variety of inflationary models. We discuss here the potential of future Cosmic Microwave Background cosmological observations in disentangling among the possible theoretical scenarios allowed by our analyses of current Planck temperature and polarization data. Rather than focusing only on r, we focus as well on the running of the primordial power spectrum, αs and the running thereof, βs. If future cosmological measurements, as those from the COrE mission, confirm the current best-fit value for βs ≳ 10-2 as the preferred one, it will be possible to rule-out the most favoured inflationary models.
