弹性散射中费米子环$W^+W^-$的重要性

Importance of fermion loops $W^+W^-$ in elastic scattering

Antonio Dobado, Carlos Quezada-Calonge, Juan José Sanz-Cillero

摘要:

我们测试的假设,费米子环的修正,高能量$W^+W^-$散射是可以忽略不计的玻色子环相比。事实上,我们发现,如果相互作用的耦合偏离了它们的标准模型值,费米子环修正实际上可以变得和玻色子环修正一样重要,甚至比玻色子环修正更重要,对于参数空间的某些特定区域,两种类型的环都应该考虑在内。一些初步的结果显示。

英文摘要:

We test the assumption that fermion-loop corrections to high energy $W^+W^-$ scattering are negligible when compared to the boson-loop ones. Indeed, we find that, if the couplings of the interactions deviate from their Standard Model values, fermion-loop corrections can in fact become as important or even greater than boson-loop corrections for some particular regions of the parameter space, and both types of loops should be taken into account. Some preliminary results are shown.
