标题： Electroweak Corrections to the Deacy $H^+\to W^+h$ in the Minimal Supersymmetric Model

摘要： 我们计算了在最小超对称模型中过程$H^+\to W^+h$的$O(\alpha_{ew}m_{t(b)}^{2}/m_{W}^{2})$和$O(\alpha_{ew} m_{t(b)}^4/m_W^4)$超对称弱电修正。 这些修正来自于第三族夸克（顶夸克和底夸克）和反夸克（顶反夸克和底反夸克）的虚粒子效应。 我们发现，在低$\tan\beta(\leq 3)$时，$m_{H^+}>200$GeV 的修正可以使树图衰变宽度和分支比分别增加超过 20% 和 40%。 显示英文摘要

摘要： We calculate the $O(\alpha_{ew}m_{t(b)}^{2}/m_{W}^{2})$ and $O(\alpha_{ew} m_{t(b)}^4/m_W^4)$ supersymmetric electroweak corrections to the process $H^+\to W^+h$ in the Minimal Supersymmetric Model. These corrections arise from the virtual effects of the third family quaurks (top and bottom) and squarks (top-squark and bottom-squark). We find that for $m_{H^+}>200$GeV at low $\tan\beta(\leq 3)$, the corrections can increase the tree-level decay widths and the branching radios more than 20% and 40%, respectively.
