标题： Formation of MACHO-Primordial Black Holes in Inflationary Cosmology

摘要： 作为对大质量致密晕天体的非重子解释，提出了一种现象学模型，该模型预测在期望的质量尺度上形成原初黑洞。 所需初始密度涨落的特征是通过利用在具有多个标量场的暴胀宇宙模型中产生的原初等曲率涨落来实现的。 显示英文摘要

摘要： As a nonbaryonic explanation of massive compact halo objects, a phenomenological model is presented which predicts formation of primordial black holes at a desired mass scale. The required feature of initial density fluctuation is realized making use of the primordially isocurvature fluctuation generated in an inflationary universe model with multiple scalar fields.
