10 Nov 2001 | | Journal: | J.Phys. G28 (2002) 169-182 | | Subject: | hep-ph | | Abstract: | We investigated the electroweak corrections from one-loop diagrams involving the third generation (s)quarks to the decay width of process $ ilde{chi}_1^+ o W^+ ilde{chi}_1^{0}$ in the framework of the Minimal Supersymmetric Standard Model. Our calculation shows that these corrections are not very sensitive to the mass of the lightest neutralino $ ilde{chi}_1^{0}$ and the sbottom mixing angle $ heta_{b}$, but depend strongly on the top squark mixing angle $ heta_{t}$ and tan$eta$. With our chosen parameters, we find that these radiative corrections can exceed 10%, therefore they should be taken into account for the precise experimental measurement at future colliders. | | Source: | arXiv, hep-ph/0111124 | | Services: | Forum | Review | PDF | Favorites | |
