The Electroweak Correction of Decay $H \rightarrow b \bar b$ in Standard Model

We re-evaluated the decay up to one-loop order of electroweak corrections in standard model with the nowadays parameters, determined by the best measurements including the latest ones from LEP and SLC. Within error range of the CDF measurement of top-quark; mass, the electroweak correction reduces the decay width less than 0.7% and the correction value varies in the range of 0.5%.
