复质量方案中ρ参数的恢复修正

Resummed corrections to the ρparameter in the complex mass scheme

D. Bettinelli, J. J. van der Bij

摘要:

给出了复质量方案中ρ参数重顶修正的全阶结果。我们推导出的复杂质量和壳方案之间的转换公式,并表明它们最终是等价的。我们表明,一个天真的治疗与固定的顶夸克的宽度不能得到甚至近似正确的结果。

英文摘要:

We present all order results for the heavy top corrections to the ρparameter in the complex mass scheme. We derive translation formulas between the complex mass and the on-shell scheme and show that they are ultimately equivalent. We show that a naive treatment with a fixed width for the top quark cannot give even approximately correct results.
