Electroweak Corrections to the Charged Higgs Boson Decay into Chargino and Neutralino

Abstract

The electroweak corrections to the partial widths of the $H^{+}\to {\tilde{\chi }}_i^{+}{\tilde{\chi }}_j^0(i=1,j=1,2)$ decays including one-loop diagrams of the third generation quarks and squarks, are investigated within the Supersymmetric Standard Model. The relative corrections can reach the values about 10%, therefore they should be taken into account for the precise experimental measurement at future colliders.
