Abstract
The supersymmetric one-loop contribution to the quark-lepton universality violation in the low-energy charged current weak interactions is studied. It is shown that the recent experimental data with the 1- deviation from the universality may be explained by the existence of the light sleptons (GeV) and relatively light chargino and neutralinos (GeV) with significant gaugino components. The sign of the universality violation is briefly discussed.
