在膨胀的宇宙中很可能发生的热平衡的破坏,允许通过违反重子数守恒的过程产生可观的重子净密度。结果表明,由此产生的重子熵比可以计算的纯微观量。
Departures from thermal equilibrium which are likely to occur in an expanding universe allow the production of an appreciable net baryon density by processes which violate baryon-number conservation. It is shown that the resulting baryon to entropy ratio can be calculated in terms of purely microscopic quantities.
