In the standard model, the Primordial Power Spectrum  can be expressed as powers of the multipole moment. This includes de scalar spectral index and may also contemplate its first and second derivatives: the running of the scalar spectral index and the running of the running respectively.Planck's latets data states that even though zero is alikely value, the interval of confidence is not centered in cero andthere are other non-zero values which are equaly probable. So a secondorder in the primordial power spectrum should be considered.
