摘要：
The nonminimal coupling to gravity -ξRφ2 2 of a composite scalar field φ is calculated in the Nambu-Jona-Lasinio model. We find ξ = 1 6. The result is exact in a leading large-N approximation, or in a fully improved one-loop renormalization group approximation. We briefly discuss some related cosmological implications. © 1992.
