NLO QCD对三玻色子产生的修正

NLO QCD corrections to tri-boson production

T. Binoth, G. Ossola, C. G. Papadopoulos, R. Pittau

摘要:

本文计算了在LHC上产生三种矢量玻色子ZZZ、W+ W-Z、W+ ZZ和W+ W-W+的非线性光学QCD修正。虚拟校正计算使用最近提出的方法减少在被积函数的水平(减少)。对于来自实辐射的贡献,我们用偶极子相减法处理软发散和共线发散。我们发现这些电弱过程的QCD修正在70%到100%之间。因此,它们必须在LHC的三重矢量玻色子生产的实验研究中考虑。

英文摘要:

We present a calculation of the NLO QCD corrections for the production of three vector bosons at the LHC, namely Z Z Z, W+ W- Z, W+ Z Z, and W+ W- W+ production. The virtual corrections are computed using the recently proposed method of reduction at the integrand level (OPP reduction). Concerning the contributions coming from real emission we used the dipole subtraction to treat the soft and collinear divergences. We find that the QCD corrections for these electroweak processes are in the range between 70 and 100 percent. As such they have to be considered in experimental studies of triple vector boson production at the LHC.
