| Abstract: | We find a new exact inflationary solution to non-minimally coupled scalar field from a specific H(φ). The inflation is driven by the evolution of the scalar field with a new inflation potential. The spectral index of the
scalar density fluctuations n
s
is consistent with the result of WMAP3 for the power-law flat ΛCDM model. Our solution relaxes the constraint to the quartic
coupling constant, e.g. when ξ=103, λ≤8.9×10−11. |
