摘要
We show that axinos produced in the early Universe in the decay of the lightest neutralinos are a compelling candidate for cold dark matter. We argue that axinos may well provide the main component of the missing mass in the Universe because their relic density is naturally of the order of the critical density. [S0031-9007(99)09187-5].
