摘　　要：本文提出了一个宇宙早期正反物质不对称性产生的模型。参照夸克模型,设想了一对新的粒子,A±这对粒子可以衰变为轻子对或由夸克组成的重子对,在宇宙早期A-和A+衰变成轻子对和重子对的比例有可能不一致,这就导致了正反物质不对称性的产生。这种方法非常新颖,而且自然和合理,符合粒子物理的理论的规律,并且克服了其它方法的不足之处。This paper presents a model for production of asymmetry of matter-antimatter in early universe.Our method is to assume a couple of new particles,A±,which can decay into a couple of leptons or a couple of baryons through referring to quark model;at early universe,the ratios of A-'s and A+'s decaying into lepton pair and baryon pair is probably not same and this results in production of asymmetry of matter-antimatter.Our method is not only very novel,but also natural and reasonable;what’s more this method coincides with law of particle physics and overcomes some defects of other methods.
