摘要：
The effect of charge symmetry breaking (CSB) due to the isospin mixing of neutral vector mesons, omega and rho(0), on nuclear matter is examined by means of a relativistic nuclear model. It is shown that a delicate cancellation between two large CSB contributions from omega and rho(0) results in a small yet significant isovector asymmetry in nuclear matter.
