| 英文摘要 | Virtual effects of supersymmetry on the partial width GAMMA(Z --> bbBAR) and on the branching ratio R(b) = GAMMA(Z --> bbBAR)/GAMMA(Z --> hadrons) are calculated in the minimal supersymmetric standard model. We found that the virtual gluino contribution to the width is negligibly small if the squark and gluino masses take the-ir experiment-allowed values. Also, we have calculated the contributions to R(b) from the charged Higgs and charginos. As to the discrepancy between two previous works about the virtual chargino correction, our calculations provide a confirmation. |
