标题： Gravitino Dark Matter and Non-Gaussianity

摘要： 我们研究了在调制再加热框架下引力子暗物质的密度涨落情景，已知该情景会产生大的非高斯性。 我们表明，在这个框架下，如果原初涨子具有大的局域型非高斯性，则引力子暗物质会被排除。 我们也简要讨论了具有曲率子机制以及其他一些可能的暗物质情景的情况。 显示英文摘要

摘要： We investigate density fluctuations in a scenario with gravitino dark matter in the framework of modulated reheating, which is known to generate large non-Gaussianity. We show that gravitino dark matter is disfavored if primordial fluctuations have large local-type non-Gaussianity in this framework. We also briefly discuss the case with the curvaton mechanism and some other possible dark matter scenarios.
