标题： Sterile neutrinos and supernova nucleosynthesis

摘要： 在超新星爆炸中，惰性中微子对r过程核合成的作用被研究。 之前有观点认为，如果超新星是重元素的起源，那么大部分中微子混合可以被排除。 结果显示，向惰性中微子的转换可能会避开这些限制。 探讨了这种转换可能增强核合成的可能性。 所需的质量谱与由其他观测现象提出的中微子质量一致，例如太阳中微子问题、大气中微子问题、暗物质和LSND信号。 显示英文摘要

摘要： The role of the sterile neutrinos to the r-process nucleosynthesis in supernova explosions is studied. Previously it has been argued that a large part of neutrino mixing can be excluded if the supernovae are the origin of the heavy elements. It is shown that a conversion to sterile neutrinos may evade those limits. The possibility that such conversions can enhance the nucleosynthesis is investigated. The desired mass spectrum is consistent with neutrino masses suggested by other observed phenomena, like the solar neutrino problem, the atmospheric neurino problem, dark matter and the LSND signals.
