暗物质粒子的质量与物态

On the Mass and the States of the Dark Matter Partcles

讨论一类与宇宙超大尺度结构有关的、稳定的弱作用暗物质粒子，它们很可能是处在简并态的费米子（也可能处在近高温态）和处在近高温态的玻色子，其质量均为～１０－１ｅＶ，而其化学势的绝对值均远小于１０－１ｅＶ。

We discuss a category of stable dark matter particles which are weakly interacting and related to the Superstructre of the universe These particles may be degenerate fermions and the bosons near a high temperature state.In both cases,we deduce that the particle mass is ～10 -1 eV and the absolute value of its chemical potential is 10 -1 eV.This result is not in contradiction with the dip phenomena of the ultra high energy primary cosmic ray spectrum at ～10 15 eV and ￣10 18 eV.
