本文提出了一种新的推导Lee-Weinberg方程的方法。这种方法使近似清晰,并建议如何改进它们。给出了湮灭过程后剩余重中微子数的近似精确公式。
A new method of deriving the Lee-Weinberg equation is presented. This method makes the approximations clear and suggest how they can be improved. A nearly exact formula for the number of heavy neutrinos left over after the annihilation process is given.
