Supersymmetric Electroweak Corrections to the Decay of the Heavy Chargino into the Light Chargino and Z Boson

The supersymmetric electroweak corrections to the partial width of the decay \tilde{χ}₂⁺→ Z⁰\tilde{χ}₁⁺, including the contributions from the third generation quarks and squarks, are presented within the minimal supersymmetric standard model. With the reasonable parameters sets, which open this decay channel kinematically, the relative corrections can reach the value of ～ -6%. Therefore they should be taken into consideration for the precise experimental measurement at future colliders.
