Abstract
We compute the one-loop supersymmetric (SUSY) contributions to the weak charges of the electron ${(Q}_{W}^{e}),$ proton ${(Q}_{W}^{p}),$ and cesium nucleus ${(Q}_{W}^{\mathrm{Cs}})$ in the minimal supersymmetric standard model (MSSM). Such contributions can generate several percent corrections to the corresponding standard model values. The magnitudes of the SUSY loop corrections to ${Q}_{W}^{e}$ and ${Q}_{W}^{p}$ are correlated over nearly all of the MSSM parameter space and result in an increase in the magnitudes of these weak charges. In contrast, the effects on ${Q}_{W}^{\mathrm{Cs}}$ are considerably smaller and are equally likely to increase or decrease its magnitude. Allowing for R-parity violation can lead to opposite sign relative shifts in ${Q}_{W}^{e}$ and ${Q}_{W}^{p},$ normalized to the corresponding standard model values. A comparison of ${Q}_{W}^{p}$ and ${Q}_{W}^{e}$ measurements could help distinguish between different SUSY scenarios.
