ILC W对产生中的次领先电弱对数

Next-to-Next-to-Leading Electroweak Logarithms in W-pair Production at ILC

J. H. Kuhn, F. Metzler, A. A. Penin

摘要:

在次-次-领先对数近似下,导出了自发破缺SU(2)规范理论中规范玻色子产生截面的高能渐近行为。在此基础上,我们得到了ILC/CLIC中W对产生的微分截面的数值增强双圈电弱修正,修正量可达大对数的二次方。

英文摘要:

We derive the high energy asymptotic behavior of gauge boson production cross section in a spontaneously broken SU(2) gauge theory in the next-to-next-to-leading logarithmic approximation. On the basis of this result we obtain the logarithmically enhanced two-loop electroweak corrections to the differential cross section of W-pair production at ILC/CLIC up to the second power of the large logarithm.
