非对易标准模型对WW散射的影响

Effects of the Noncommutative Standard Model on WW scattering

John A. Conley, JoAnne L. Hewett

摘要:

我们研究了用Seiberg-Witten映射构造的非对易标准模型中W对的产生。考虑分波么正性的反应WW WW WW和e+e-WW表明,后者的过程是更敏感的,树级么正性被违反时,散射能量的顺序TeV和非对易尺度低于约TeV。我们发现,WW生产在大型强子对撞机是不敏感的尺度以上的么正性界限。然而,在e+e-湮灭中的WW生产提供了一个很好的探测器,在LEP-II中排除了低于300-400 GeV的非对易尺度,并且ILC对高达10-20 TeV的尺度敏感。此外,我们发现,在ILC的最终状态W玻色子的螺旋度状态的测量能力提供了一个诊断工具,以确定和解开不同的可能的非对易贡献。

英文摘要:

We examine W pair production in the Noncommutative Standard Model constructed with the Seiberg-Witten map. Consideration of partial wave unitarity in the reactions WW to WW and e+e- to WW shows that the latter process is more sensitive and that tree-level unitarity is violated when scattering energies are of order a TeV and the noncommutative scale is below about a TeV. We find that WW production at the LHC is not sensitive to scales above the unitarity bounds. WW production in e+e- annihilation, however, provides a good probe of such effects with noncommutative scales below 300-400 GeV being excluded at LEP-II, and the ILC being sensitive to scales up to 10-20 TeV. In addition, we find that the ability to measure the helicity states of the final state W bosons at the ILC provides a diagnostic tool to determine and disentangle the different possible noncommutative contributions.
