We point out that, since the colliders' initial states ( e(+)e(-),pp, p&pmacr;,ellipsis) carry a definite non-Abelian flavor, electroweak radiative corrections to inclusive hard cross sections at the TeV scale are affected by peculiar Bloch-Nordsieck violating double logs. We recall the setup of soft cancellation theorems, and we analyze the magnitude of the noncanceling terms in the example of electron-positron annihilation into hadrons.
我们指出，由于对撞机的初始状态（e(+)e(-)、pp、p&pmacr; 等等）带有确定的非阿贝尔味，在 TeV 尺度下对包含性硬截面的电弱辐射修正会受到违反布洛赫 - 诺德西克的特殊双对数的影响。我们回顾软抵消定理的设定，并在正负电子湮灭成强子的例子中分析未抵消项的大小。
