Abstract

Supersymmetric one-loop contributions 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 1σ deviation from the universality may be explained by the existence of the light sleptons (<220 GeV) and relatively light chargino and neutralinos (<600 GeV) with significant gaugino components. The sign of the universality violation is briefly discussed.
