摘要：

The ratio R(T) of K+-C-12 to K+-d cross sections has been calculated microscopically using a boson-exchange KN amplitude in which the sigma and omega mesons are dressed by the modifications of the Dirac sea in nuclear matter. In spite of the fact that this dressing leads to a scaling of the mesons effective mass in nuclear matter, the effect on the R(T) ratio is found to be weak.
