英文摘要:
We re-evaluated the decay H --> b (b) over bar, 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%.
