We present a model of exclusive ϕ-meson lepto-production $ep\to e^{\prime }{p}^{\prime }\varphi$ near threshold which features the strangeness gravitational form factors of the proton. We argue that the shape of the differential cross section $d\sigma /dt$ is a sensitive probe of the strangeness D-term of the proton.

φ邻近阈-meson lepto生产和奇异d -term

我们提出独家ϕ-介子妖怪制作的模型$Ëp\to {Ë}^{\prime }{p}^{\prime }\varphi$接近阈值，具有质子的奇异引力形状因子。我们认为微分截面的形状$d\sigma /dŤ$ 是质子奇数D项的灵敏探针。
