The Role of the Curvaton Post-Planck
The Role of the Curvaton Post-Planck
The expected improvements in the precision of inflationary physics observables including the scalar spectral index $n_{s}$ and the tensor-to-scalar ratio $r$ will reveal more than just the viability of a particular model of inflation. In the presence of a curvaton field $\chi$, supposedly dead models of inflation can be resurrected …
