We forecast the scientific capabilities of CORE, a proposed CMB space satellite submitted in response to the ESA fifth call for a medium-size mission opportunity, to improve our understanding of cosmic inflation. The CORE mission will map the CMB anisotropies in temperature and polarization in 19 frequency channels spanning the range 60-600 GHz. CORE will have an aggregate noise sensitivity of $1.7 mu$ K$cdot ,$arcmin and an angular resolution of 5′ at 200 GHz. We explore the impact of telescope size and noise sensitivity on the inflation science return by making forecasts for several instrumental configurations. This study assumes that the lower and higher frequency channels suffice to remove foreground contaminations and complements other related studies of component separation and systematic effects, which will be reported in other papers of the series “Exploring Cosmic Origins with CORE.” We forecast the capability to determine key inflationary parameters, to lower the…
