标题： Cosmology Based on f(R) Gravity Admits 1 eV Sterile Neutrinos

摘要： 研究表明，最近中微子振荡实验倾向于支持质量约为1 eV的惰性中微子，而宇宙学数据通过密度涨落的自由流阻尼对中微子质量施加了严格的限制，这种矛盾可以在基于f(R)引力理论的当前宇宙加速膨胀模型中得到解决。 显示英文摘要

摘要： It is shown that the tension between recent neutrino oscillation experiments, favoring sterile neutrinos with masses of the order of 1 eV, and cosmological data which impose stringent constraints on neutrino masses from the free streaming suppression of density fluctuations, can be resolved in models of the present accelerated expansion of the Universe based on f(R) gravity.
