  "abstract": "We study the purely gravitational production of a massive vector dark matter with a non-minimal coupling to the Einstein tensor, $ξG_{μν}X^μX^ν$, in warm inflation. The background, $V=λϕ^4$ with a dissipation coefficient linear in temperature, is constrained by CMB observations and parametrized by the dissipation ratio $10^{-4}\\le Q_0\\le1$. We consider both unavoidable production channels: freeze-in from the Standard Model bath through graviton exchange, and cosmological gravitational particle production (CGPP). For freeze-in, we compute the scattering amplitudes including the contact interaction induced by $ξ$, which enhances the production of light dark matter through the longitudinal mode and suppresses that of heavy dark matter through destructive interference. For CGPP, the slow-roll parameter is not small during warm inflation, which enhances the production of light dark matter by up to three orders of magnitude relative to cold inflation. Combining both channels, CGPP excludes most of the light freeze-in branch, leaving $m_X\\lesssim2.4\\times10^{-5}$ GeV, a narrow window around $10^{10}$ GeV for strong dissipation, and $m_X\\gtrsim10^{14}$--$10^{15}$ GeV. Only the heavy branch remains viable for all $|ξ|\\lesssim1$.",
