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