'''Non-minimally coupled inflation''' is an [[cosmic inflation|inflationary]] model in which the constant which couples [[gravity]] to the [[inflaton field]] is not small. The [[coupling constant]] is usually represented by <math>\xi</math> ([[Xi (letter)|Xi]]), which features in the [[action (physics)|action]] (constructed by modifying the [[Einstein-Hilbert action]]):<ref name=hertzberg12>Hertzberg (2010-02-16), p. 1–2</ref>

<math>
S = \int d^4x \sqrt{-g} \left[{m_P^2 \over 2} R - {1 \over 2}
\partial^{\mu}\phi \partial_{\mu}\phi - V(\phi) - {\xi \over 2} R
\phi^2\right]
</math>

<math>\xi</math> represents the strength of the interaction between <math>R</math> and <math>\phi</math>, which relate to the curvature of space and the magnitude of the inflaton field respectively.
