摘要：

We suggest a three stage mechanism for the development of a net baryon excess in the universe. The first phase is an initial heating due to strong gravitational fluctuations during the first 10-43 s. This is followed by a stage in which baryon and CP violating processes produce a large excess via a mechanism suggested by Weinberg. Finally thermalization dissipates most of the initially produced baryon number leaving a small excess. © 1979.
