Query: From New to Large Field Inflation: Comparison with WMAP3   We briefly summarize and update a class of inflationary models from the early
eighties based on a quartic (Coleman-Weinberg) potential for a gauge singlet
scalar (inflaton) field. For vacuum energy scales comparable to the grand
unification scale, the scalar spectral index n_s=0.94-0.97, in very good
agreement with the WMAP three year results. The tensor to scalar ratio r<~0.14
while alpha=dn_s/d ln k=~-10^-3. For vacuum energy scales >~10^16 GeV, the
inflationary scenario switches from `new' to `large-field' (V\propto\phi^2)
inflation. An SO(10) version naturally explains the observed baryon asymmetry
via non-thermal leptogenesis.
