Abstract: | We predict the quantitative lifetime differences of weakly decaying charmed baryons which arise due to preasymptotic bound state effects. These predictions are to a large extent model independent. We also give and compare detailed quantitative estimates obtained in a nonrelativistic quark model and in a bag model. Finally, we show how the various nonspectator effects can be separated and determined phenomenologically, once the lifetime of charmed baryons are measured with sufficient accuracy. |
